Lea Thompson and writer Bob Gale on the 35th anniversary of ‘Back to the Future’

The first “Back to the Future” movie hit the big screen in 1985. It was written by Bob Gale and Robert Zemeckis, who also directed the film. Michael J. Fox played Marty McFly in all three movies, but he wasn’t originally cast in the role. Actor Eric Stoltz got the part, and six weeks into production was replaced by Fox. “You could feel it,” Gale tells Yahoo Entertainment about bringing in Fox. “This kid is great. He really is Marty McFly. The movie is going to work with him in the lead.” Lea Thompson remembers the casting shakeup being “weird.” She recalls getting phone calls from executive producer Steven Spielberg and director Zemeckis about Stoltz being fired. “I was like, ‘Oh my god, they fired me,’” she says. Thompson says working closely with Fox “was really fun.” “I love him to this day,” she adds. “He’s a funny wonderful man.”
