Pierce Brosnan Says He Is "Less Macho" After Filming "Mamma Mia"

Pierce Brosnan admits he lost his macho image while filming new movie "Mamma Mia!."

The former James Bond star says singing and dancing for his role as Sam Carmichael in the big-screen version of the Abba-inspired musical did little to confirm his status as a tough guy.

He said: "I'm the last person you would expect to see pouncing around in platform shoes, tights and sequins. We had to do all these camp, dainty little moves and try to look butch. That was a challenge."

Brosnan's co-star Colin Firth also admits his reputation was put on the line and he never had any ambition to star in a camp musical based on the hits of the successful Swedish band.

Firth, who plays Harry Bright in the movie, revealed on British TV show 'The Mamma Mia! Story': "Very few straight males of my generation would have put their hands up and claimed to have been an Abba fan in the 70s. In fact if I had a crystal ball in 1976, and seen this is sort of the thing I'd end up doing, I probably would have put a bullet through my head."

"Mamma Mia!" - which tells the story of a young girl's search for her father, with two of the potential dads being played by Brosnan and Firth - has its U.K. premiere tonight.
