Sophie (Amanda Seyfried) is a free-spirited 20-year-old who lives on a Greek island with her mother (Meryl Streep). Before she gets married, she invites three men (Pierce Brosnan, Colin Firth, and Stellan Skarsgard) to the island to find out which one of them is her father. Mamma Mia! is a fun, silly movie that'll bless you with enough Abba covers to hum along to all Summer.
