Clint Eastwood convinced Charlie Sheen to go to rehab after family intervention led by Martin Sheen

Sheen, 60, reflected on his addiction journey and the way his famous family organized an intervention in the early '90s in the new Netflix documentary, "aka Charlie Sheen."

"I think Mom called me: 'Dad's got things to do, so we have to do it early.' She's like, 'We're thinking 9:00.' I'm like, 'a.m.?' She's like, 'Yeah.'"

His longtime friend, Sean Penn, did not participate. Penn said in the docuseries that he was "never involved with those interventions" due to his own personal struggles.

"I was not, you know, walking a perfect trail of my own in some regards," Penn said.

Sheen remembered staying mostly silent during the "emotional" day, where his friends and family read letters.

"There's a lot to process," he said. "I'd kind of heard about these things, but never been this close to an intervention." Sheen requested time away from the group to think about going into treatment, but "they said, 'No. This is a decision we've made for you that has to happen today.'"

He added, "I was figuring, 'If I just agree to this, just to get out of this situation, I can probably hatch a plan somewhere away from here.'"

Sheen was deep in thought on ways to avoid getting treatment until his dad walked out of his office and said, "There's someone on the phone who wants to talk to you."

"It's a very recognizable, very globally familiar voice," he said. "It's Clint."

Sheen finally got clean in 2017. "You have to be willing," he told People magazine. "I keep a [mental list] of the worst, most shameful things I've done, and I can look at that in my head if I feel like having a drink."
