Usually, when you hear that the studio slashed a movie’s budget and forced major changes, it’s a bad sign. That’s not the case with Back to the Future, which turned 40 last year. The studio cut the movie's budget, forcing director Robert Zemeckis to change the ending. Even he agrees it made for a far better moment than the original idea. The movie, one of the best of the ‘80s, has proven incredibly enduring, and I think we can all agree that the ending, with Doc (Christopher Lloyd) up on the clock and Marty (Michael J. Fox) timing his run at 88 mph, is a classic. It was almost very different.
