Corrected entry: When Marty buys the sports almanac, how does he get the money to do it? Considering a Pepsi costs 50 bucks, the almanac probably costs several hundred dollars. How many teens from the 1980's just happened to have that amount of money in their wallet at any given moment? He didn't get the money from Doc since Doc didn't even know he bought it until after the fact.calidude
Corrected entry: Marty sees himself talking to his parents one last time before his other self goes to meet Doc at the clock tower. At this point Biff steps up to Marty and comments on his disguise. The problem here is that in the first movie Biff is never seen again after George punches him. If he had woken up he would have been there to confront the first Marty at the door after telling his parents about the burned carpet, or even George for hitting him. So what happened to Biff the first time if he wasn't there when '55 Marty walked out the door?
Corrected entry: After Doc and Marty leave the cafe 80's to get Jennifer back from her 2015 house, you see old Biff retrieve the sports almanac from the trash can, he then audibly says "so Doc Brown invented a time machine!" Next scene in the DeLorean, Doc says he thought he saw something in his rear display, a shot of a yellow cab is then displayed. No way for old to Biff get a cab and catch up so fast, as the DeLorean had been parked in an alleyway, with no cab in sight.John D 619
Corrected entry: When the "old Biff" steals the time machine in 2015, as Doc and Marty attempt to retrieve Jennifer, it shouldn't be possible for Biff to return to the world that exists around him, as he gets out of the car back in 2015. Doc, Marty, Jennifer, and the world around them ALL should no longer exist, while still trying to escape from 2015. An alternate time line should have been created the moment "old Biff" left 1955. (Thus, Doc's explanation to Marty via the chalkboard explaining an "Alternate Reality"). This all started in 1985, and one result of old Biff's ventures, we learn that Doc is committed to an institution and couldn't even invent, or at least complete, the time machine by October 26th, 1985, which is the starting date of the initial film.BLuRD
Corrected entry: When Biff and his gang crash through the windows of the clock tower with their hover boards, Marty goes to give his back to the little girl, but she says "keep it, I've got a pitball now" and shows him Biff's hover board. Only problem is it's still in the clock tower wreckage, attached to the other 3.
Corrected entry: When Marty confronts Biff in 2015 and asks when, where, and how he got the sports almanac, Biff retrieves it from a safe and a lock box and carefully shows it to Marty. Because the almanac contained results from sporting events through the end of the century (the year 2000), it would have been rendered worthless 15 years before and would therefore no longer need to be kept in a safe, if even at all.jds122567
Corrected entry: When Old Biff hands Young Biff the Almanac, the book passes through the film split (the vertical bar that divides the windshield) perfectly because it was on a motorized rig. But the stand-in for Old Biff didn't hold his arm at the right height, so Old Biff's arm disappears into the bar that runs down the middle of the window while the book floats across to Young Biff.
Corrected entry: Considering the sports almanac contains 50 years of statistics in all major sports, it is very small and thin, about the size of a magazine. This would work if it only contained major sporting event results (super bowl, world series) but obviously it doesn't. It has results from horse races in small towns like Hill Valley listed and regular season college football scores. The font size of the printing in the book would literally have to be microscopic in order to contain all the info it does. Even college football alone, listing just Division 1 teams, would require several hundred pages.calidude
Corrected entry: When Marty's son walks by young Jennifer in the hallway of his home, he thinks is the older Jennifer and says "Hi mom, nice pants". Later at dinner, Marty Sr. and Lorraine are talking about how Jennifer is late coming home. Marty Jr. is sitting right there and doesn't even mention how he just saw his mom in the hallway.calidude
Corrected entry: In the year 2015, Marty's daughter Marlene is telling Lorraine that the reason the scenery channel isn't working is because the scene screen repairman called Marty a chicken and Marty threw him out of the house. Why would the repairman call Marty a chicken? Nothing at all makes sense about this, what could possibly provoke a repairman to call the owner of the home he was working in a chicken ? Even if Marty was rude to him, it would make more sense to just call him a jerk, not a chicken. Calling him a chicken likely means he was goading him into a fight and there is no logical reason for some repairman to want to pick a fight with someone he is servicing.calidude
Corrected entry: After Marty burns the sports almanac, it is only burning for a few moments before it begins to pour rain. There was not enough time to burn the whole book, considering he started the fire with some cheap matches and no gas or lighter fluid to make it burn faster. Some of the pages may have survived. There would have been water damage from the rain on the remaining pages for sure, but a few pages may have still survived and have been legible enough for a passerby (or maybe even the western union guy) to be able to read and use to make bets.calidude
Corrected entry: In the scene where Doc lands the DeLorean in pouring rain in 2015, after a while the rain stops, and it is sunny and you can see the clock tower is in full light when Marty looks at the newspaper. But when Marty, after putting on his new clothes, walks on the street, it is cloudy again.
Corrected entry: The cooling vents on the back of the DeLorean change between silver and black throughout the film. A clear example of this is the first landing scene of the DeLorean in the alley in 2015.
Corrected entry: When Marty and Doc successfully save Marty's son from going to prison in 2015, the USA Today headline spontaneously changes while Marty holds it. If this is possible, then, when Biff steals the DeLorean to deliver the almanac to his younger self, Marty and Doc's memories would be instantly replaced by those of the alternate 1985 - which would mean that Marty would not be baffled by bars on his windows or locks on his gate when he arrives back home there. In fact, they wouldn't have returned to that house at all.
Corrected entry: After Biff steals the DeLorean and travels back to 1955 with the Sports Almanac the movie states that he creates an alternate time line. Doc Brown does a good job of illustrating this on a chalk board. So if, as Doc Brown states, Biff created an alternate time line, then when he travels back to 2015 it would be the year 2015 on the alternate time line.
Corrected entry: How did 2015 Biff know how to operate the time machine well enough to get himself back to see 1955 Biff? He learns about the existence of the time machine from an overheard conversation, which does not include any details of how to set the time circuits nor the requirement to accelerate the car to 88 mph in order to start the time jump.
Corrected entry: In the scene in 2015 where the future Lorraine and George McFly come to eat dinner at Marty and Jennifer's house, Lorraine cooks a pizza in a toaster oven. After cooking for 3-4 seconds, Lorraine removes the pizza, which is sizzling hot. However, Lorraine removes the hot pizza with her bare hands without burning herself.
Corrected entry: Doc puts Jennifer to sleep because she was asking too many questions about her future, and according to him, no-one should know too much about their future. But when they have landed in 2015, Doc doesn't see anything wrong with telling Marty, at length, what is going to happen to Marty in his future.
Corrected entry: In Back to the Future 1 after Marty goes to 1955, you see a sign that says "Hill Valley 2 Miles". Later in the movie, Marty talks to George and Lorraine then walks out the door. The next scene you see Marty with Doc in his 1985 explaining that he needed to change his clothes, and than there is the whole sequence where Marty goes back to 1985. In 1955, in Back to the Future 2, Marty is standing outside the gym when Biff approaches him. Marty is knocked down by his earlier self, and Biff steals the Almanac. Then Marty steals the Almanac, burns it, sees Doc get struck by lightning, receives the telaeraph, runs 2 miles back to Hill Valley, just to meet Doc after his previous self goes back to 1985. How is it possible for on Marty to do the thing previously stated, while the other one dresses and drives to the Clock Tower, taking up the same amount of time?
Corrected entry: The two theories of time travel displayed in the Back to the Future series seem to conflict with each other. In the first movie, Marty changes history to create a future where he was never born, and as a result he begins to fade out of existence. In the second movie, Biff changes history to create a future where Marty is away at boarding school, but rather than fading into his new timeline, Marty stays exactly the same. There are now two Martys, one from 1985 (Marty 1) and one from 1985A (Marty 2). If that's the case, then Marty should have stayed exactly the same in the first movie (Marty 1) and returned to an alternate universe where his other self (Marty 2) was never born.
Corrected entry: When Marty is talking to the Doc when he is in the back of Biff's car, it shows the present Doc with the past Doc's hair (i.e. the actor has the wrong wig on). It cuts back to Marty, then back to the Doc, where he still has the past Doc's hair. When it cuts back to the Doc a third time, he has the present Doc's hairstyle.
Corrected entry: During the scene where Marty has to duck and move past the car with his other self and Lorraine inside the car, he hears his other self ask Lorraine if she smoked too, in which she replied, "You're beginning to sound just like my mother." Then Marty hears his other self say, "Yeah right.". Problem is, in the first Back To The Future, after Lorraine said that, Marty never said "Yeah right."
Corrected entry: In one scene, Doc Brown says that the year 1955 might be the junction point for the entire space/time continuum. 1955 WAS a big year for space travel, as it was the year that President Eisenhower entered America into a competition to send up a sattelite by 1957.(Our sattelite was called Project Vanguard; Russia won with Sputnik). Thus the space race actually started in 1955.
Corrected entry: Doc and Marty learn the date when Biff was given the Almanac. It turns out that this is also the date of the events in the first film. Doc then surmises that they will not only have to avoid detection by Old Biff but also by their 'other' selves. All that considered, does it not seem a little reckless to return to that date? They have a Time Machine, and the book is useless to Biff until he turns 21 which would be 1958 at the latest. That's a whole three years and Doc could have chosen from any day he wanted to retrieve the book but he picks the day where they run the greatest risk of screwing up time even more. Given that he's always lecturing on the consequences of messing with time, and that their entire future depends on him succeeding, it seems a little out of character for Doc to not even consider the possibility that they go back to a different day.
Corrected entry: After Marty burns the almanac in 1955, he looks at the newspaper that he has with him and sees that it is changing. One of the stories that changes is "Nixon to Seek Fifth Term; Vows End to Vietnam War by 1985" to "Reagan to Seek Second Term; No Republican Challengers Expected." Reagan wasn't looking for a second term in 1985 because he won it in 1984.
Corrected entry: As Marty sees his other self talking to his parents, Biff appears and challenges Marty to a fight. When Marty walks away Biff calls him a chicken. Marty walks up to Biff and when he says "Nobody calls me chicken" he gets hit by the door and even though you hear the word chicken, Marty's mouth doesn't move when he says it.
Corrected entry: You'll need slow-mo and pause for this one. When Griff's three mates throw down their hover boards they actually throw them beyond the camera, then digital super-imposed ones land in front of them. Watch closely at the girl's board (on the right) it's transparent, then the guy in the middle jumps beyond the camera and again super-imposed legs land on the hover board.
Corrected entry: When old Jennifer and young Jennifer see each other in 2015, they faint. (Earlier on Doc mentioned that if they saw each other, either the space time continuum would stop, or something like that or they would merely faint.) This being so, then how come when old Biff and young Biff see each other in 1955, neither of them faint.
Corrected entry: In the scene where Marty is watching his other self talking to his parents (his other self just played Johnny B. Goode), he is watching through the door, when suddenly Biff turns up and they argue. When they are about three feet away from each other (just enough space for a door to be opened) you see Marty blinking his eye, because he expects the door to be slammed open, and the Marty from the first film rushes out.
Corrected entry: When Marty's daughter answers the door she lets in Grandma Lorraine and Grampa George. Lorraine says that she brought pizza for everyone. Marlene says "who's going to eat all of that" and Grampa George says "I will." Yet, when the pizza is hydrated, Grampa George is not in the kitchen at the table or in any of the following house scenes.
Corrected entry: When Doc and Marty are on their way to get the Jennifer of 1985 Doc says "Damn this traffic. Jennifer, that is the old Jennifer, usually gets home around this time." However Marty of 2015, when his mother asks where Jennifer is, says he doesn't know and that she should have been home hours ago. I don't think it took Doc and Marty hours to get to the house so Doc was way off with his calculation.
Corrected entry: Marty of 2015 is in the kitchen with his mother and two kids. We hear a phone ringing. Marty takes the call in the den and gives a verbal command "hello, in here please" as the words "incoming call" are flashing. After Needles hangs up we see and hear "thank you for using AT&T". Right after that, without any phone ringing, incoming call flashing, or Marty giving a verbal command to accept the call, his boss just pops up on the screen. Since the screen is two-way this would be an incredible invasion of privacy. The phone needed to ring and Marty needed to give a verbal authorization in order for his boss to be received.
Corrected entry: In 1955, Biff is told by Terry (the mechanic) that the bill for fixing his car after the manure accident was $302. Even deducting the $80 charged by Old Man Jones for hauling the manure away, that would be $222 just for a little bodywork and an inside valet. That's pretty expensive for today, let alone for 1955. I doubt that buying the car itself would have cost Biff much more than $300, especially since it's a 1940s model - so he can't have got it new. (Or perhaps he inherited it, along with the money he had: he lived with his grandma, so his parents were presumably dead). Since the same dirty accident befell him again later that very day, did he then try to minimize the bill by cleaning the car out himself? Perhaps that's how he got started on valeting cars for a living.
Corrected entry: Why is it that when in the first film when Doc grabs the door handle of the time machine when it comes back to normal time with Einstein in it and gets hurt by the extreme cold, but when he grabs the hood of the DeLorean in the second film to give Marty the walkie-talkie, he doesn't have a reaction at all?
Corrected entry: In the beginning of the movie, when Doc takes Marty and Jennifer "back to the future", we see the DeLorean float up and make the usual sparks and fire trails in the air as it makes the time jump. The fire trails are below the car as if the tires were also in their original positions. They aren't - they are tucked up horizontally.
Corrected entry: Marty and Doc need to go to Biff's casino hotel to find out the exact date of when old Biff gave the almanac to young Biff. However, the time circuits tell where they most recently were in time. So after old Biff came back to 2015 after stealing the time machine, they should have noticed that he had gone to 1955 to give the almanac away.
Corrected entry: The crashed Parkers' car is not the same car they had in first movie, when Jenn's dad came to take her - it has round lights, the previous one had rectangular.
Corrected entry: When Doc and Marty arrive in the alternate 1985, they drop off Jennifer and Marty goes to his house as if nothing is different (sans the bars Marty notices on her windows). But after Marty finds out it isn't his house, the streets are filled with destroyed cars, chalk outlines, gunshots are heard everywhere, and houses are on fire. Did they miss all this during the drive in?
Corrected entry: As Marty and Doc fly away from Biffs hotel, Doc enters the Nov.12.1955 date then seconds later is shown to be switching on the circuits. Doc even says "Time circuits on" as he does this. The problem is that the circuits have to be already on in order to enter the destination date (as shown in BTTF 1).
Corrected entry: The old Biff gets the Almanac in 2015, steals the DeLorean, heads to 1955, gives the almanac to his younger self, and then heads back into the future, right? According to the Back To The Future way of explaining how time works and how events change the future, shouldn't he have gone back to the ALTERNATE future, instead of the future he left?
Corrected entry: In the scene where Doc is hovering the Delorean behind Biff's car, as Marty puts his feet on the hoverboard, the camera overtakes the Delorean, the driver of which is not Doc. Whoever it is simply puts his hand up towards the camera, to cover his face (but just slightly too late).
Corrected entry: In the scene where Biff gets the sports almanac from "Gramps" Biff in his garage, Gramps gives Biff the sports almanac. Biff looks at it, makes a dumb comment and then gets slapped for it, then tosses it in the backseat. But you'll notice Gramps still has the almanac in his hands and uses the book to show the results of the UCLA game. When Biff is given the book for the second time, it is tossed in the backseat again.
Corrected entry: The money ratio in 2015 seems incorrect. When Doc sends Marty into Cafe 80's he hands him a $50 for a Pepsi. In another scene when Marty is walking outside, Old Terry asks Marty for $100 to save the clock tower. Usually a soft drink would cost more than what a man waving a can would ask for. Then when old Biff gets out of the taxi, his total comes to $174.50. According to the price of a Pepsi, doesn't this taxi ride seem cheap?
Corrected entry: In the DVD version, if you watch the deleted scenes, it shows old Biff Tannen returning to the future after giving himself the almanac and then being erased from history, probably because Lorraine shot and killed him in 1995. Here is the hugest paradox ever. If Lorraine shot and killed Biff in 1995, then how could Biff grow up to be old Biff and steal the Delorean and give his younger self the almanac in the first place? Also, immediately after old Biff gave his 1955 self the almanac, shouldn't old Biff have immediately been erased from existence while still in the year 1955?
Corrected entry: In the tunnel chase scene where Marty is on the hoverboard and Biff is in his car, after Marty gets the almanac, Biff drives to the end of the tunnel and spins his car around. The next shot is a close up of the front of Biff's car and you can clearly see his license plate. The year is supposed to be 1955, but his tags expired in 1951.
Corrected entry: After Marty talks to his parents after playing on stage he casually strolls out the door just opening the door a fraction, but in Back to the Future 2 he knocks his other self unconscious by flinging the door open. That shot was seemingly done again for the second movie so Marty could be knocked unconscious.
Corrected entry: When Doc, Marty and Jennifer go into the future, they disappear above the Mcfly home, but when they arrive in 2015, they are outside Hill Valley (although after they disappear into the future there is a long 'journey' when the credits are showing, with enough time for them to get out of Hill Valley, but after the 'journey' the car makes the swooshing noises it does when it arrives somewhere, so this was just for the credits).
Corrected entry: When Biff is at the Enchantment Under the Sea dance he tells principle Strickland that he is not old enough to drink alcohol. At Biff's hotel the movie that plays says that he won at the track on his 21st birthday in 1958. When Doc stole the newspapers from the library there was an article about Biff's winnings dated in March of 1958. If Biff was 21 in March of 1958, then he was 18 in November of 1955, and since the legal drinking age was 18 in 1955 he was, in fact, old enough to drink alcohol.
Corrected entry: When Doc opens his case full of currency, it's sorted by decades, and Doc explains that it's purpose is to be ready for all monetary situations. He pulls some currency from the stack labeled 1950's and tells Marty to use it to buy some clothes. However, since the year they are in is 1955, there's a chance that he may be giving Marty money dated anywhere from 1956-1959. Wouldn't it have made more sense to take the currency from the stack labeled 1940's instead, thereby not running the risk of drawing attention to themselves with money printed with 'future' dates?
Corrected entry: We see that George McFly died in 1975 when Marty checks the newspaper; the article on the front page says he was murdered, with a sub headline that reads "Local Author Dies." However as we saw in the original Back to the Future, George didn't get his first book until 1985 when Marty came back from 1955. Therefore George was not an author in 1975 when he was murdered. Even if in the alternate future George wrote earlier, when Doc and Marty fixed the future the newspaper should not say "Local Author Honored" because in the non-alternate future he was not an author until 1985.
Corrected entry: At the end of the film, as the DeLorean gets struck by lightning, Doc goes back to 1885. We then hear Marty reading from the letter that the lightning strike damaged the flying circuits on the car. So how did he land it in 1885 from the 40 feet altitude he was at when struck by the lightning, if the car couldn't fly in order to land safely?
Corrected entry: This is the part in the very beginning when Doc takes Marty and Jennifer to the future. Wouldn't the future be without Marty and Jennifer because they left in 1985 and must have been missing all that time. From 1985-2015. Thus, there would be no way in heck that they would have existed in 2015, and no way that the 1985 Jennifer would have seen herself or her house, family etc.
Corrected entry: When Marty is at the Enchantment Under the Sea dance at the end of the movie, he's trying to get the sports almanac from Biff. But then Mr. Striklin takes the Magazine from him and goes to his office, and throws it in the garbage. Marty then immediately gets it out, only to realise that it is just the almanac cover, with an Oh La La magazine inside. Therefore the coverless almanac is still in Biff's hands, so Marty crumples the cover, throws it on the ground, and runs after Biff. Then, When he is chasing after Biff again to get the REAL magazine, the cover is once again on the magazine, in Biff's hands.
Corrected entry: At the end of BTTF, we learn that Doc is alive because he did indeed find Marty's letter. And we know that he had to tape it together because he ripped it to pieces. Now at the the end of part 2 upon seeing Marty reappear after he has sent him back to the future he faints. Now wouldn't this alter the timeline because he never goes through the trash to get the letter therefore he won't be prepared in the future with his bullet proof vest?
Corrected entry: At the end of BTTF, Doc, Marty and Jennifer take off for the future. In BTTF2, they arrive 30 years later and see themselves. Impossible! They would have been inside the time machine (as far as those left behind are concerned) for 30 years. Marty and Jennifer were gone from 1985 to 2015 as far as he and everyone else knows. I can prove this by using the first movie. When Einstein goes into the future one minute, he was gone for a minute as far as Doc and Marty were concerned, even though the trip was instantaneous to Einstein.
Corrected entry: When Marty from Back to the Future I leaves George and Lorraine out the back door of the gym he opens the door so hard that he hits Marty of BTTF II and knocks him down. Watch Back to the Future I and see how far Marty actually opens the door. He barely opens it enough for himself to fit through. In other words, he would have never been able to knock himself out.
Corrected entry: Griff and his gang crash into the courthouse on their hoverboards, yet a minute later, the little girl has the same hoverboard Griff was riding. Even if Griff flew off the board, it would still land on the other side of the water or in the water. The little girl is on the opposite side.
