Back to the Future

Corrected entry: White screens used for lighting are reflected on Marty's sun glasses, when he is boosted backwards by the amp. (00:04:35)

Correction: Watching the scene frame by frame on BluRay, you can see reflected in Marty's sunglasses that there are 2 bright windows. They are not white screens because you can see the window panes in his glasses. The same windows with panes are seen right after he answers Doc's phone call to Marty (the windows in the background that were right in front of Marty).

Corrected entry: After Marty returns to the present, he wakes up in his room that is identical to the beginning of the movie, however the rest of the house i.e the living has changed and is more modern.

Waldo Gonzalez

Correction: That merely tells us that Marty was more or less the same in both timelines, having similar tastes.

Which wouldn't happen. Because with loving, successful and self confident parents, there's no way a kid turns up just the same as with goofy, drunk, and pushovers parents.

Corrected entry: When Biff takes Marty out of the car in 1955, he says, "You caused $300 damage to my car, Mcfly!" The only person who knew he was a Mcfly was Doc Brown.

Kenziemama73

Correction: The line Biff says is "You caused $300 damage to my car you son of a bitch", he never addresses him as McFly. The TV-edited version might have changed the line, but that's not a movie mistake.

Corrected entry: Marty's sister stated at the dinner table that grandma hit his dad with the car, but in the 1955 scene it was the grandfather that hit him.

Correction: She says Grandpa, not Grandma.

Thomas Norris

Corrected entry: Plutonium is not a red liquid, it is a white-silver coloured metal. Even oxidised in solution it would be paler than shown.

Correction: It wouldn't be safe to use plutonium metal. Even with the suits on, both Marty and Doc would be subject to lethally high amounts of beta and gamma radiation. Chances are they used a dilute solution (possibly plutonium (IV) chloride as that is red in colour) and it is possible to deeper red is down to dye or impurities in the solution - the latter is possible as Doc acquired it from terrorists.

Corrected entry: When Marty escapes the Libyans at the Twin Pines Mall, hits 88mph and ends up in Old Man Peabody's barn, driving in through a large opening in the barn before crashing. However, the cut to the inside of the barn shows no form of entry other than the closed doors the family are entering. In addition the inside of the barn is very small compared to the outside view. (00:30:10 - 00:31:55)

Paul Andrews

Correction: He doesn't enter the barn where the family enters the barn. He enters through the back of the barn and goes all the way through, hence why the family are facing the lights from the door they enter through, not the back of the car.

Corrected entry: In the speaker explosion scene at the beginning of the film, a horizontal safety line can be seen attached to the waist of the stunt person as he is knocked backwards.

Correction: This is the guitar cable which connects Marty's guitar to the amplifier.

Corrected entry: Steven Spielberg makes a cameo as the jeep driver with a green cap who pulls Marty around the street.

ozwal13

Correction: That is not true. The jeep driver is Walter Scott (who is also credited for his role).

Bishop73

Corrected entry: Einstein, Dr. Emmett's dog is the first to travel in the time machine. He travels one minute into the future during which he ceased to exist in the current time only to reappear one minute later. According to this it hence would be impossible for the Doc, Marty and his girlfriend, Jennifer, to travel into the future and see their futures as they would have ceased to exist as of when they left the current time until they reappear in the time they set hence impossible to have continued their normal course of life and exist in the future.

Correction: The series makes it clear that the timeline is highly resistant to changes, and that when you make a change to the timeline, there's a delay before those changes impact the timeline. This is why Marty saw the photo of him and his siblings slowly fading rather than instantly disappearing as soon as he interrupted his parents' getting together. In the second movie, Jennifer and Marty weren't in the future for long enough to start impacting the timeline.

Corrected entry: When Marty is trying to prove his futureness to Doc, he says that his sister was in the class of 1984 and then shows Doc a picture. Whenever the picture is shown however, the shirt says class of '81.

Correction: There's a vertical fold in her sweatshirt causing the '4' to be compressed so it looks like a '1' if you don't look too closely.

Corrected entry: When Lorraine follows Marty back to Doc's in 1955 and Doc goes to answer the door, he says to Marty (before opening it) that it's his mum. Lorraine must have heard them through the door yet she never questions it.

Heather Benton Premium member

Correction: Two possible reasons she never asks about it. First, she simply did not hear him. You're assuming she did, but there's no evidence of it. Second, asking questions would be tantamount to admitting to eavesdropping. It's rude to eavesdrop and so Lorraine would hardly give herself away by asking questions about something she wasn't supposed to have heard in the first place, and which would have sounded nonsensical anyway.

Corrected entry: The original DeLorean tops out at a measly 80 miles per hour and that is probably with a tail-wind downhill. However, it is likely the Doc heavily modified the engine to reach 88 miles per hour.

Correction: The DeLorean DMC-12 had a listed top speed of 130 MPH, and Road & Track tested the 0-100 MPH acceleration time. While it's performance figures were criticized as being somewhat disappointing, the DMC-12 could easily reach 88 MPH even without any modifications Doc would've done.

Corrected entry: This one is tricky but important in view of Doc's concern about doing anything that will alter the future. The lightning rod on the clock tower would have been connected to ground with a thick cable. Doc would have had to disconnect this cable to allow the current from the lightning to flow into his cable instead and hence to the time machine. We now know that a lightning strike is a result of a complex interaction of electric potentials between charges in a cloud and charges in the ground below. By disconnecting this grounding cable this interaction would have been disrupted, causing the lightning to strike at a different time or strike a different object on the ground.

Correction: If you touch a lightning rod while lightning strikes it, you will still get electrocuted. So, just like the energy would travel into your body, it traveled through Doc's cable. No need to disconnect the ground. If grounding a power source kept it from charging any thing else, no electrical appliance would ever function.

Corrected entry: Early in the film, Mr. Strickland tells Marty that he is a slacker and that he reminds him of his father because he was a slacker too. However, it is extremely unlikely that Mr. Stickland should even remember who George McFly is. How many school administrators can remember some random student from 30 years prior? It would make more sense if he was George's teacher because teachers can have a close relationship with their students, but as a school administrator, there have literally been tens of thousands of students under his watch during his 30 year tenure at Hill Valley High School. It's not as if George ever did anything to stand out. He was not a star athlete or a valedictorian and never did anything noteworthy in his life in the original timeline. He was not a troublemaker either, so it's not as if he would have spent a lot of time in Strickland's office. He should have been a nameless face in the crowd as far as Strickland was concerned, so hard to believe he would still remember such a random person after 30 years. I have only been out of high school for 13 years myself and if I ran into my old principal in the street tomorrow, I can guarantee that he wouldn't be able to remember me to save his life.

Correction: George did do something to stand out. He did nothing! Strickland hates slackers and clearly remembers them. One of my guidance counselors in jr. high was my father's guidance counselor and knew exactly who my father was based on my last name alone 21 years later. Some people just have very good memories for names and faces.

Grumpy Scot

Corrected entry: When Marty begins playing "Johnny B. Goode", the guitar tone is suddenly distorted whereas it was clean in the prior song without him ever adjusting the amp or the guitar's volume knob. The guitar also becomes more distorted during the guitar solo.

Phaneron Premium member

Correction: Turning a knob on a guitar takes almost no time at all. He could have easily turned it between shots, or when his back was turned toward the camera.

MasterOfAll

Corrected entry: In the original film Doc rips up Marty's letter and then sellotapes it back together at some point, however at the end of the second film Doc faints, so he wouldn't have picked up the letter and should be dead.

Correction: Doc never picks up the letter because he never let it go in the first place. He rips it up and *puts it in his pocket*. Presumably the pieces are still in the pocket when he faints and subsequently wakes up in his home.

JC Fernandez

Corrected entry: When Marty travels back to 1955 the DeLorean first strikes a scarecrow, then drives at high speed into a barn and finally crashes through the barn door to escape. Later, when it returns to 1985, it crashes into a movie theatre front before it can stop. After all this mayhem the DeLorean doesn't have as much as a scratch on its nose.

Correction: That's because the entire body of every DMC DeLorean is made out of stainless steel, not fiberglass.

Corrected entry: Mayor Red Thomas in the 1950s based on his picture, looks to be around age 50. However, in 1985, when he is a bum, he still looks about the same age, even though he should be around 80 years old now. Granted, some people age better than others, but it is doubtful that an old man living on the streets would even survive for very long, let alone age gracefully.

calidude

Correction: You are assuming Red has lived on the streets for a long time. We have absolutely no information about how long he has been a bum; he could just as well be a youngish-looking 80-year-old who just recently suffered a decline in fortune and became homeless as a result.

Twotall

Corrected entry: After Marty changes things and returns to 1985, he finds his brother Dave is more successful and now has an office job. So why is Dave still living at home with his parents?

calidude

Correction: This has already been asked. He never says he lives there. He may be just having breakfast with his sister and parents on his way to the office. Also, if he's living with his parents, it wouldn't be a mistake. Many young adults continue to live with their parents, just because they don't have to spend extra money.

Corrected entry: When Marty first enters Lou's cafe in 1955, Lou is visibly angry at Marty just because he won't order something right away. However, he doesn't seem to care that one of his paying customers, George McFly, is being harassed by Biff and his gang and told never to come in there again. You would think Lou would tell Biff and Co. to knock it off or else be asked to leave.

calidude

Correction: George had already paid for his cereal, what does Lou care? Biff and Co. are paying customers on occasion too, he wouldn't want to alienate them either. Especially considering they're likely to vandalize his restaraunt in retaliation.
