Rainn Wilson Larry White in 'THE LAST MIMZY'

Director BOB SHAYE failed to spot just how much was revealed in one scene, in which Wilson, the star of America's THE OFFICE, wore just a pyjama shirt until the film hit test audiences.

Wilson explains, "Bob was very excited about me doing the scene without any pyjama bottoms on for some reason; I think he had a thing about my ass.

"We shot it and, of course, sure enough they started testing it and family people were like, 'Wait a minute why is this guy's ass poking out.'

"So they had to digitally CGI on a pair of $40,000 boxers. It's there in the current print of the film. When I bend over at the refrigerator you see leopard-print boxers under my pyjamas. It's probably the most expensive underwear in movie history."
