5. Shia LeBeouf
The star of the popular Disney Channel Show, Even Stevens, LeBeouf seemed like he would have a fantastic career after Disney. He seemed to be on the right track earning roles in the 4th Indiana Jones film and the Transformers franchise.
However, after a period of odd behavior (LaBeouf attended the Nymphomaniac premiere with a paper bag over his head in 2014), he was arrested later that year and charged with harassment, disorderly conduct, and criminal trespassing after disrupting a performance of Cabaret on Broadway.
