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."
