In 1984, production started on Back to the Future with Eric Stoltz as Marty McFly instead of Michael J. Fox. After 5 weeks of filming, Stoltz had to be let go – a decision that cost the studio just over $3 million. According to Zemeckis and Spielberg, Eric Stoltz, though he was a fantastic actor, was just not naturally funny enough for the film.
