Character mistake: Before playing Johnny B Goode Marty says it's a blues riff in B, but then plays the song in B-flat.

Character mistake: In the parking lot when Marty begins to film, Doc says the date and exact time according to his watch. Marty then looks at his watch. Apparently his is off because he shakes his wrist and puts the watch to his ear to see if it is still working. However, he is wearing a digital watch which wouldn't tick or likely have broken parts to rattle.

Questions

Question: Right when Marty gets back to Doc before he goes back to 1985, he's praising his dad's actions of the night. One line that's bothered me ever since I can remember is "My dad laid out Biff. He's never stood up to Biff in his life." And then the Doc pauses for a second and gets a strange look on his face and says, "Never?" To that, Marty says, "No, why?" and the Doc shrugs it off saying, "Nevermind." What's Doc thinking? The best I can come up with is that he's wondering what effects it'll have on the future, but that's a rough guess. If anyone out there knows, I'd be happy to hear it.

Chosen answer: I think that is *exactly* what he is thinking. He realizes that by standing up to Biff, George may have irrevocably changed his personal future, and therefore affected Marty's future as well. This is exactly the sort of thing Doc was so eager to prevent by refusing to hear any information about the future.

Answer: It would have had to be something that would have happened anyway without the interference, otherwise Marty wouldn't have originally existed.

Answer: In the novel Marty adds that George is also thinking about college now. Doc says that this might delay Loraine and George having kids for awhile and adds that Marty might find himself like 10-14 years old when he gets back to 1985.
