Although Michael J. Fox was the first choice for the role of Marty McFly in Back to the Future, due to scheduling conflicts with his hit TV series Family Ties, the part was given to an actor named Eric Stoltz. After several weeks of filming, it was clear Eric was wrong for the role. Producers arranged for Michael to film the movie evenings - he was picked up after shooting of Family Ties finished each day and driven to the Back to the Future set, where he worked until the early hours of the morning and the rest, as they say, is history. On the other hand, Christopher Lloyd was the first choice to play Doc Brown and when offered the role, he was initially going to turn it down but after meeting with screenwriter Robert Zemeckis, he changed his mind. In the movie, when Marty meets Doc Brown in the parking lot of a suburban shopping mall, he gets into the scientist's DeLorean time machine and goes back in time and changes history. At least, Marty’s family history, that is. He has to make things right before he can go back to the future.
