Ewan McGregor has confessed to being "disappointed" that American audiences won't get to see him in his full glory in upcoming movie Young Adam.

A full frontal scene featuring the Scot actor - most famed for his role in Trainspotting - has been cut from the US release of the film over fears that it could cause offence to some cinema-goers.

"If you want to see my penis, you’ll have to fly to Britain," McGregor told Premiere magazine. "If I’d blown away 5,000 people with a semiautomatic machine gun, that would be fine. But I showed my penis."
