Charlie Sheen doesn’t listen to many people, especially when it comes to his hard-partying. But there’s one person whose advice apparently did resonate: Clint Eastwood. Sheen revealed on the TV sports show Centerstage that the Oscar-winning actor took part in an intervention with family and friends during the peak of Sheen’s troubles, ultimately convincing him to go into rehab. “There’s a phone call at the very end [of the intervention], and it’s Clint Eastwood,” said Sheen. “And he says, ‘Come on, kid, you know, you’re tougher than this, just go fix yourself, get back in the game.’ And I was like, ‘Alright, Clint.’ How do you say no to Dirty Harry, you know? So I went [into rehab]… It helped at the time.” Sheen and Eastwood had become friends after working together on the 1990 film The Rookie. But it doesn’t seem like rehab taught Sheen much. He recently said he doesn’t believe in it. And the contents of his tiger blood are open to speculation after he refused to take drug tests with FX during production of his current show Anger Management—and gave a mysterious, poetic response when confronted by drug allegations earlier this year.
