Ewan McGregor at the Premiere of 'Thank You Philip Morris' the 2009 Sundance Film Festival, Day 4. Park City, Utah - 18.01.09

The Star Wars star joined comedian Ferguson for a skit on his U.S. late-night programme The Late Late Show on Friday night (15May09) and donned a fuzzy ginger wig and stick-on moustache to play a convincing Russian soccer star.

Ferguson, playing retired fictional English sports ace-turned-commentator Dirk Weems, suddenly realised he'd slept with the mother of McGregor's character.

The two pals struggled to keep straight faces as McGregor's moustache kept peeling away from his top lip.
