Back to the Future Part II

Corrected entry: You have to really listen carefully but when the Doc says "Griff's gonna ask you about tonight" he says "Biff" by accident. (00:08:45)

Correction: Character mistake. The names are so similar, and Doc is more accustomed to saying "Biff".

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.

Correction: Marty's mouth moves when he says the first part of the word, then he is getting hit by the door as he continues talking, so that's why his mouth can't be seen moving for the rest of it.

Corrected entry: When Marty is back in 1955, he goes to Strickland's office to get the almanac back. He looks through the window, and sees Strickland sitting in his chair with the almanac. He is looking through some sort of mesh on the window. When he goes into the office, the mesh is gone.

Correction: The wire in the glass is always there. It can be seen by looking closely. It's just not as obvious in shots where the window is in the background because the wire is thin and the silver color of it tends to make it blend in with the glass at a distance.

Corrected entry: When Biff and Marty discuss the Almanac in the Alternate 1985, a magazine is visible. This is the March 1989 issue of "Mustang."

Correction: They are discussing a "book" that is brought back from the future while in an alternate universe of sorts, but another book dated a few years ahead in time is out of the question? They have a time machine at their disposal, and could have brought back any item they wanted, as it is illustrated that they did indeed travel forward in time to an "antique" shop in the future.


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. (00:18:00)

Correction: Slow-mo AND pause? This is so difficult to see even when using slow-motion that this certainly does not class as a mistake.

Corrected entry: When Marty does the "switcheroo" in the hotel stairwell to avoid rich Biff's thugs, a crew member's shadow is easily visible at the spot Marty jumps to. This can be seen right before the camera pans upwards to reveal Marty a few flights up running towards the roof.

Correction: I've watched this over and over again in slow-motion. The extra shadow also belongs to Marty. Marty has more than one shadow due to the lights from the stairwell shone all around him. The way this extra shadow moves matches Marty's movements perfectly.

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.

Correction: The 2015 Biff knows he is going back to meet his old self, obviously, because he is doing it, and 1955 Biff doesn't recognise 2015 Biff as a version of himself - he refers to his old self as 'that crazy old codger with a cane.'

Corrected entry: When Marty is watching his other self talking to his parents, Biff's shadow can be seen on the wall. He is waiting for his cue.

Correction: The only time Biff's shadow is visible is a split second before he comes on camera. This is quite natural, as he is walking up to Marty at the time. It might ruin the surprise a little, but there is no reason why his shadow should not be there.


Corrected entry: When Lorraine is telling Marty, "That was very interesting .... music.", watch her lips. Her mouth and the words don't match.

Correction: I just watched that shot repeatedly, and saw nothing wrong with her mouth movements. They matched the words just fine.


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.

Correction: There is no mistake here. Marty is expecting the door to be slammed open because he remembers how he left the building. The timing might seem funny, but he could have remembered just at that second.

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.

Correction: Any number of explanations. Grandpa George could have been in the bathroom, for all we know.

K.C. Sierra

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.

Correction: The time a person "usually" gets home is not the same as the time a person gets home on a particular day. The family expected her home hours earlier THAT DAY. That doesn't mean they expected her home hours earlier EVERY day.

K.C. Sierra

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.

Correction: Given that this is a fictional movie set in the future, there is no way to be sure how their video phone system works. Perhaps Marty's boss has some type of override to where he can talk to his employees directly in just this sort of situation. After all, if you just did something where you know you could get fired from your job, would you want to talk to you boss? Probably not.

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.

Correction: With labor fees going through the roof nowadays, even little dings and dents from very minor traffic accidents can cost sometimes even in the thousands to have repaired. Considering Biff obviously sustained some minor car damage from first striking the manure truck, not to mention the labor and such to remove all the manure itself, $300 seems fairly appropriate for what something like that would have cost in 1955.

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?

Correction: This is a question, not a plot hole. And to answer, the DeLorean has been to the future at this point, where it could have gotten any number of modifications we don't know about (we see the hover conversion and Mr. Fusion, but who's to say he didn't do something about the freezing? Maybe some kind of instant heater if the car drops below a certain temperature?).

Nick N.

Corrected entry: Marty, Jennifer, and Doc Brown travel to the year 2015. Shortly after landing the Delorean in an alley, if you look at the wall that leads out of it, you will see spray-painted on a wall the words "Class of '16".

Correction: It is quite common to refer to your future senior year of graduation, even while you're a freshman - so a freshman in September of '80 is part of the Class of '84, and that is what he/she will think of for the next four years.

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.

Correction: As seen in various shots throughout the trilogy, most notably the first time the Delorean jumps through time in the first movie, the fire isn't coming from the wheels, but some sort of vent located just behind the rear wheels. Even though the wheels have moved for the car's flight mode, those vents may have stayed in their previous position, leaving the trails beneath the car as it is in the film.

Corrected entry: When Marty and the Doc arrive in 2015, it is 4:29AM. However, when they arrive in Hill Valley, the sun comes out from behind a cloud, high in the sky.

Correction: Actually, Doc says it's 4:29 PM, not AM.

Corrected entry: When Marty is on the roof with Biff in the new 1985 he jumps off the roof onto the DeLorean. Yet when he jumps off you don't hear one sound of him hitting the car.


Correction: We aren't supposed to hear him hitting the car. The producers were just trying to create a little bit of suspense to give us that "What's going to happen next?" feeling. If we heard Marty hitting the car, the suspense wouldn't exist.

Corrected entry: When the DeLorean travels forward through time at the beginning of the first movie, it gets covered in ice. During all other subsequent time travel, this does not happen.

Brian C Friesner

Correction: It does happen again, it's just harder to notice. For all we know it only affects the car on very short time travel trips, with the car being warmer the further back or forward it goes.

Back to the Future Part II mistake picture

Continuity mistake: Notice Marty's hair in the scene when he's playing "Johnny B. Goode." It's quite larger than when he says, some seconds later, "I guess that you're not ready for it yet." That's because when he says that, it's a recycled shot from the original BTTF, whereas most shots showing he's playing the guitar are newly made for BTTF2. However, Marty's hair is considerably longer in the new shots.

Trivia: In an interview, the director stated that hoverboards were real, but they weren't on the market because parents didn't like the idea of floating children. He said this as a joke, but this didn't stop mass hysteria as thousands of kids went from store to store looking for hoverboards.
