Back to the Future Part II has one of the more bewildering plots of any movie I count among my favorites, and a wild theory about it occurred to me a few years ago. I've never heard anyone else propose this theory, but it resolves several plot holes and makes sense on its own terms, once you think it through. My theory is that Doc's true motive in taking Marty to 2015 isn't to help Marty's son as he claims, but to teach Marty a lesson that will help prevent the accident that destroys Marty's musical aspirations.

The scene at the end of the first film, replayed at the beginning of the second, raises a number of questions. In this scene, Doc assures Marty that "you and Jennifer turn out fine," and that the problem is that "something has got to be done about your kids." After he takes Marty and Jennifer to visit the future, however, these statements don't match up with what we see. The middle-aged Marty from 2015 hasn't exactly turned out fine, and only one of Marty's kids needs help. Why did Doc mischaracterize the situation?

It should be noted that the filmmakers have stated in interviews that they created this final scene before they had any real plans for sequels. As such, Doc's statements were probably just throwaway lines they found amusing at the time. But that doesn't explain why, when working on the second and third film, they chose to contradict Doc's statements.

The entire scene was re-shot for the second film, ostensibly because the actress who played Jennifer in the first film, Claudia Wells, had been replaced by Elisabeth Shue. Somebody pointed out to me a subtle difference between the two versions of the scene, which are otherwise quite identical. In the Claudia Wells version, Doc's line "you and Jennifer turn out fine" is spoken smoothly and confidently. In the Elisabeth Shue version, Doc visibly hesitates before saying the line, and he utters it a bit too rapidly to sound convincing.
