There was one interviewer Charlie Sheen turned down on his self-described odyssey: tough-talking British television host Martin Bashir.

The former Nightline host, who defected to MSNBC last year, had approached the now fired Two and a Half Men star to do another no-holds barred tell-all at his 'Sober Valley Lodge' mansion in Los Angeles.

"After much debate and discussion with his advisors, Charlie drew the line at Bashir," said one source familiar with last week's negotiations.
