1) Charlie Sheen
Charlie Sheen once held the title of America's highest-paid television actor for his stint in Two and a Half Men. Sheen went through a public meltdown and engaged in a bitter feud with the show's creator, Chuck Lorre, which got him fired. In the year 2021, Sheen told Yahoo! Entertainment that his behavior back in the year 2011 was desperately juvenile. He also almost claimed that he would have been better off accepting the advice of the then-CEO of CBS, Les Moonves, who told him to go to rehab. Though Sheen tried for a comeback with Anger Management, the reality show wasn't good enough for him. Nevertheless, his reputation and personal problems made it hard for him to keep up with the fast-paced demands of studio environments.
