Charlie Sheen Thanks Fans, CBS for Support

Feb. 2, 2011— -- Charlie Sheen, in a written statement, thanked fans, co-stars and CBS -- especially Les Moonves and Bruce Rosenblum -- for their support as he undergoes rehab.

"I have a lot of work to do to be able to return the support I have received from so many people," Sheen's statement said. "Like Errol Flynn, who had to put down his sword on occasion, I just want to say, 'thank-you.'"

Sheen voluntarily checked into a rehab facility last week, prompting CBS Entertainment and Warner Bros. Television to put his hit sitcom, "Two and a Half Men," on an indefinite hiatus.

His statement came just hours after Los Angeles Fire Department officials released a five-minute 911 call from Dr. Paul Nassif, who said he had received a call from the actor, according to The Associated Press.

"They said, 'Don't call 911,' but I got [Sheen] on the phone and he was very, very intoxicated, also apparently in a lot of pain," he said on the call.

"All I know is I got a secretary who called and said he's in severe pain and is intoxicated. He said he's very worried but he said don't call anybody."

Sheen's recent problems are bad both for the network that airs "Two and Half Men" and the studio that produces it. They could lose hundreds of millions of dollars if "Two and a Half Men" fails to return to TV.

But for those around Sheen, his latest (third) round in rehab comes as a relief. A source close to the situation told ABCNews.com that high-level executives at CBS and Warner Bros. have been pushing for Sheen to go to rehab for some time.

A CBS statement released Monday underlined that point: "The most important thing right now is that Charlie is seeking help. Any immediate programming or financial implications pale in comparison to his long term health, safety and well-being."

It might be better for Sheen to return to work sooner rather than later. With family out of his reach -- his eldest daughter recently got married, his two young daughters are in the custody of his ex-wife, Denise Richards, and his twin baby boys are in the custody of his estranged wife, Brooke Mueller -- his job seems to be the only thing keeping him on track.

In October, while "Two and a Half Men" was on a scheduled hiatus, Sheen partied with an adult film star, went on a rampage through New York City's Plaza Hotel and landed in the hospital.

Last week, while the show also was on a scheduled hiatus, he again partied with an adult film star and landed in the hospital before revisiting rehab.

"When he's working, he's good at keeping it all together," said People magazine senior writer Joey Bartolomeo. "When he's not working, that's when bad things happen."
