Production of "Two and a Half Men" went on hiatus in January 2011 while Sheen underwent a substance rehabilitation program in his home, his third attempt at rehab in 12 months. The following month, CBS canceled the season's four remaining episodes after Sheen publicly made derogatory comments about the series' creator, Chuck Lorre, and Warner Bros. banned Sheen from entering its production lot. Sheen, already the highest-paid actor on television, responded by publicly demanding a 50 percent raise, claiming that in comparison to the amount that the series was making, he was "underpaid".
