A video making its way around today offers up a great walk down memory lane. Can you imagine anyone else except Michael J. Fox starring in Back to the Future? Well, Eric Stoltz was the original choice but was recast 5 weeks into the film’s production. The clip below features Steven Spielberg, Robert Zemeckis and (co-writer) Bob Gale explaining the switcheroo. The clip is part of the extras on the DVD and Blu-ray release of the trilogy on October 26.
