Charlie Sheen admits he was out of control

"It was like a runaway train that I was kind of the reluctant conductor of. And it just kept going. I said some things that were a little out there. I might have overshot the mark a little bit," Sheen said.

"But these were just metaphors...These were just jokes," Dailystar.co.uk quoted him as saying.

"I was out of control absolutely. I think it's important that people see, that I see, and that I feel, that was just one crazy chapter and one weird phase. I was this guy before it started and so I can be that guy again afterwards," he said.

Sheen was fired from the show early this year after publicly feuding with producers and series creator Chuck Lorre - and the incident sent the actor on a downward spiral.
