Back to the Future: Part II opens with the ending scene from the first movie. But anyone who has seen the movie more than once will know that the sequence was completely reshot. I’m sure there are a multitude of reasons why they didn’t just use the same footage, including the fact that Claudia Wells, who played Marty McFly’s girlfriend Jennifer Parker in the original film, had been recast with 1980’s movie hottie Elizabeth Shue. Also, the movie was shot nearly five years later, so they probably wanted Marty and Doc’s appearances to seem consistant with the rest of the film. But even then, they needed to try to make the reshot sequence look almost exactly the same as what was shown in the original film. The “a rejuvenation clinic” excuse Doc gives Marty once they arrive in 2015 was likely a excuse to get rid of the old man make-up Christopher Lloyd was forced to wear in the 1985 scenes of the original film.

Justin Taormina has put together a video comparing this repeated sequence. Hit the jump to watch it now.
