10. Robert Downey Jr.

The turn of the new millennium was a tough time for Robert Downey Jr. Although he is now known for being the smooth talking hottie and star of the Iron Man movies, he had a rough patch back in 1999-2000. He was in court for violating his parole requirements and revealed that he had been a long-running drug addict. Some time behind prison bars and troublesome law-breaking situations left us looking at a torn and debilitated actor. He was addicted to cocaine and methamphetamine, but seemed to have recovered from the horrific meltdown. Now he is starring in uber-successful movies and still making women swoon.
