The same producers who brought the musical Mamma Mia! to the stage are bringing it to movie audiences, so fans shouldn't worry about whether the film version soundtrack satisfies -- it does. Granted, these actors aren't known for their singing ability, but they may surprise you. Meryl Streep can indeed sing -- and sing well -- as shown on the heartfelt "Winner Takes it All." Newcomer Amanda Seyfried (Mean Girls) is a revelation with her clear, colorful vocal range, and even the dashing Brosnan manages to carry a tune, albeit a little lackluster, but we'll forgive his mediocrity because we know how good he looks while he's singing the tunes on the big screen. The Broadway musical was a hit because of the great music and heart-warming, funny story. The same wonderful music carries onto the movie soundtrack, so fans get a little more of what they already love.
