18. Charlie Sheen
While known more recently for some of his antics, many forget that Charlie Sheen once was a very well respected actor. He came to prominence in many of Oliver Stones movies including Platoon and Wall Street. What many also forget is that he followed the same path that his very famous father, Martin, did by taking a role in a Vietnam War film. Martin Sheen, star of Coppolas Apocalpyse Now, advised his son to stay away from Platoon. Despite this, Charlie took the role and became a big star. As a reward, Oliver Stone cast both father and son in his next film, Wall Street.
