Robert Downey Jr.

Downey started out in Hollywood as a fresh-faced teenager. He had a lot of good scripts under his belt and was a very talented actor. But like his character in Less than Zero, he started getting hooked on drugs and fell from grace the worst possible way. He spent a little shy of a year in a Californian state facility and prison after several parole violations connected to the drug charges attached to his name. He slowly climbed his way to the top, and now, people see him as a true hero – Iron Man has risen and has become better than ever.
