Reuters has a Q&A with John Travolta to promote his animated film "Bolt." At the end, they ask him about his biggest career regrets.
Tom Hanks listen up!
Q: Which parts do you most regret turning down?
A; "'Chicago' probably (Travolta was offered the role of Billy Flynn). I wasn't all that into the stage show. It was a lot of women who hated men and I like women who like men. (laughs) The stage show was kind of vicious but the movie had a heart. 'Green Mile' I probably should have said yes to and 'An Officer and a Gentleman'. But I gave Richard Gere and Tom Hanks a career! What you turn down can be a gift to someone else. There is enough to go around."
