Back in 1990, Charlie Sheen's interventions were somewhat more star-studded, he told CenterStage this weekend. In fact, when friends, family, and Sean Penn gathered that year to coax Sheen into rehab, there was a late-breaking intervention cameo from his co-star in the film The Rookie. "There's a phone call at the very end, 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." And it clearly took, the end.
