It’s no secret that actress Claudia Wells was replaced in the second chapter of the Back to the Future Trilogy. It wasn’t that big of a deal considering the actress was barely even in the first movie. She was the token girlfriend and irrelevant to the plot until the second movie (You and Jennifer turn out fine… its your KIDS!!) and all the subsequent appearances of Marty’s girlfriend were then played by Elizabeth Shue – still a relatively minor role.
But as the storylines overlap, the very beginning of Back to the Future 2 used the closing moments of Back to the Future to kick off the story, but this time they had to reshoot the scenes with Shue in place (and include Biff seeing the flying DeLorean taking off)
Check out this side by side of the two scenes.
It is neat to see the two side by side like that, seeing the upgraded video, effects and obviously how Michael J Fox had aged slightly.
