Original Australian Daybill movie poster. Teen Wolf is a 1985 American fantasy comedy film directed by Rod Daniel and written by Jeph Loeb and Matthew Weisman. The project came together when Michael J. Fox accepted the lead role and his Family Ties co-star Meredith Baxter-Birney became pregnant, which created a delay in the show's filming that allowed Fox time to complete filming and then return to his TV show. Released on August 23, 1985, Teen Wolf debuted at No. 2 in its opening weekend, behind Back to the Future.
