Actor Tom Arnold, who helps stage recoveries for addicted celebrities, says he approached one of Charlie Sheen’s close friends about getting help for the star. "I went to a person close to him and said, ‘This guy is in serious trouble with serious drugs. We’ve got to help him,’ ” Mr. Arnold tells The New York Times. “And this person flat-out told me to my face, ‘We make a lot of money from him. I can’t be part of it.’ That tells you everything you need to know.” After two years of trying to convince Sheen to seek help, CBS finally shut down production of Two and a Half Men after the star reneged on an agreement to enter rehab. One source says Sheen used his money-making power to keep any kind of morals provision out of his CBS contract that would allow him to be fired or replaced for bad behavior.
