Corrected entry: When Marty is trying to recover the future copy of the sports almanac from the office of Mr. Strickland, he sees that inside the almanac's cover is a dirty magazine. ("Oh La La"). After Strickland leaves the office, Marty tears the almanac cover off, crumples it up, and throws it on the ground, leaving it there. Later, at the dance, BTTF2 Marty is knocked down by a door that is thrown open by the BTTF1 Marty and Biff sees the, now intact with no crumpled cover, almanac inside Marty's leather jacket. Biff then takes it, never replacing the Oh La La inside with the almanac contents. (01:21:00 - 01:40:00)
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 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: 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: 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: 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: 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. (01:28:47)
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: 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: 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: 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: 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
