Back To The Future star Crispin Glover will never marry, because it would interfere with his acting career. The 42-year-old actor, who played MARTY MCFLY's dad GEORGE in the 1980s sci-fi classic, deliberately goes out with women who aren't looking for commitment. He tells RetroCrush.com, "I've never been close to being married. I don't know if I'll ever get married. "I think that marriage really is important for having children. At this point in my life the most important thing is making films... A child for me would be extremely distracting. "I go out with women that don't want to get married, which is fine with me. I have no troubles with that."
