MAMMA MIA MERYL!

Multiple Oscar-winner has done just about every accent and hair color known to man. She's also tried her hand at almost every genre of film there is - except musicals. Well, that's all about to change as the Devil Wears Prada star is reportedly set to star in the big-screen version of hit Broadway musical Mamma Mia, which features the cast singing a number of classics from '70s Swedish pop stars ABBA. According to reports, the film, executive produced by and wife Rita Wilson, should go into production later this year.
