Jon Cryer had no idea his former Two And A Half Men co-star Charlie Sheen was heading for a major meltdown, insisting "nobody was prepared" for such headline-grabbing behaviour.
Sheen was fired from the hit sitcom in March (11) following months of wild antics, a health emergency, rehab and his bitter media blitz.
Cryer admits he was caught off-guard by the sudden onslaught of Sheen's personal and professional problems because he didn't see any warning signs.
He tells U.S. talk show host David Letterman, "We didn't see where it was going. This has never happened before. Honestly, it wasn't like, back in 1963 everybody remembers when Fred MacMurray went bats**t and started talking about Freemason ninjas and stuff. He was crazy! And Vivian Vance started urinating on the set of Here's Lucy. You remember that? That was great fun! Nobody was prepared for this. I did not see it coming. Nobody saw it coming...
"None of us wanted to continue with the show if we felt it was hurting him, and there was a point when everyone felt like... there was no control here... When (the show was temporarily) shut down, it was the end of the world for some people. There are a lot of fans of the show... and when we shut down, it hit people hard."
But Cryer is adamant he wants Sheen to put his problems behind him and "get healthy", adding, "I want him to stay sober, I want him to be reunited with his family: That would be the best thing."
Ashton Kutcher has since been hired to replace Sheen on Two and a Half Men.
