Eric Stolz was originally cast as Marty McFly when first choice Michael J. Fox was unavailable due to his shooting schedule on Family Ties. But on Jan. 10, 1985, after about six weeks of filming, the actor was fired due to his style being deemed too intense and not comedic nor manic enough. An arrangement was then made to bring Fox aboard even as he continued to film Family Ties.
