Actor Colin Firth is convinced his famous co-stars are a bunch of "drag queens" because they're secretly only interested in playing dress-up.
The 'Mamma Mia!' star joins Hollywood legends Meryl Streep and Pierce Brosnan as the trio sing and dance on film for the summer Abba-inspired movie musical.
And Firth says the experience has left him certain that his fellow actors' best inspiration came from their mother's closets.
He muses: "Actors are basically drag queens. People will tell you they act because they want to heal mankind or, you know, explore the nature of the human psyche. Yes, maybe. But basically we just want to put on a frock and dance."
