46 of 48: Robert Downey Jr., 45, was in-and-out of rehab between August 1996 and 2001, having been frequently arrested for various drug-related charges. Downey spent time at the California Substance Abuse Treatment Facility and State Prison in 2000, and upon his release found some success acting on "Ally McBeal." But after another relapse and one more stint in a court-ordered drug treatment program, Downey has finally remained sober and taken control of his career. ( Photo / Flickr)
