Back to the Future Part II
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.

Continuity mistake: In the beginning when Doc takes Marty and Jennifer to 2015 for the first time, they are descending towards Hill Valley. Doc turns the steering wheel to the left but the car goes right and down. (00:05:53)

Deliberate mistake: When Old Biff and Young Biff are sitting in Biff's car, the car's rear-view mirror vanishes during all shots of Old and Young Biffs together. Presumably this made the split-screen effect easier to do.

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.

Trivia: When Doc and Marty arrive back in 1955 to stop the handover of the Almanac, there are 4 versions of the time machine in the area at that time - the one they just arrived in from the alternate 1985, the one Marty arrived in from the original 1985 in the first film, the one Biff arrived in from 2015 in the second film, and the one Doc buried in 1885 in the third film.

Biff: Look, Lorraine, you walk out that door and I won't only cut off you, I'll cut off your kids.
Lorraine: You wouldn't!?
Biff: Oh, wouldn't I? First your daughter, Linda. I'll cancel all her credit cards. She can settle her debts with the bank all by herself. Your idiot son, Dave. I'll get his probation revoked. And as for Marty. Well, maybe you liked to have all three of your kids behind bars just like your brother Joey. One big happy jailbird family.

Biff: Go ahead, kid. Jump. A suicide will be nice and neat.
Marty: What if I don't?
Biff: [raising gun] Lead poisoning.
Marty: What about the police, Biff? They're gonna match up the bullet with that gun.
Biff: Kid, I own the police. Besides, they couldn't match up the bullet that killed your old man.
Marty: You son of a...
[Biff pulls back on the gun's hammer.]
Biff: Suppose it's poetic justice. Two McFlys with the same gun.

Marty: You're not going to believe this. We have to go back to 1955.
Doc: I don't believe it!

More quotes from Back to the Future Part II

Question: In the alternate 1985, there is an alternate Biff, Lorraine etc. Shouldn't there also be an alternate Marty and Doc?

Answer: Yep, and there is, but they're both elsewhere. Doc's been committed to an asylum somewhere. When Marty first meets the alternate Biff, Biff tells him that he's supposed to be in Switzerland at boarding school - that's where the alternate Marty is.

Wouldn't someone probably see Doc and report that he escaped from the asylum?

Maybe, but no way to be sure, and they're not around long enough for that to be an issue anyway.

Answer: Doc would most likely not have been seen by anyone, as the time he spent in the alternate 1985 was primarily inside the DeLorean, at a boarded-up library, graveyard, and his lab (and all at night too) so most likely not spotted by the public.

Question: Doc Brown strongly believes that nobody should ever find out about their own future. With such a strong conviction, why would Doc tell Marty that his children going to prison is the one event that would ruin the whole McFly family?

Answer: At the end of the first film, Doc says, "what the hell" in response to the letter Marty gave him. So this shows it is not that strong a conviction, especially in the face of definite knowledge about something bad happening. It is also a way for Doc to repay Marty.

MasterOfAll

Answer: Doc advises Marty to not tell him about his future because it may affect his life. It doesn't matter what happens to his kids at all.

Question: What song does Marty play on his guitar in 2015 after he gets fired?

Answer: He is attempting to play the song "The Power Of Love" by Huey Lewis and The News. He was first seen playing it very well in the first Back To The Future movie when he was trying out for the school dance. Jennifer recognizes the song and is shocked that Marty who was so good at guitar was suddenly able to hardly play it.
