Amanda Seyfried struts her singing stuff in 'Mamma Mia!'

IN THE HBO series "Big Love," Amanda Seyfried plays the eldest daughter in a polygamist family of one husband and three wives. In the lavish new musical "Mamma Mia!," based on the long-running Broadway hit, she plays the only daughter of one mother and one of three boyfriends. ¶ In the movie that features the music of '70s band ABBA as prominently as any of its stars, Seyfried plays Sophie, the daughter of single mom Donna (Meryl Streep), who operates a small hotel on a beautiful Greek island. For Sophie's wedding, Donna invites her BFFs (Christine Baranski, Julie Walters) who were the backup singers of her old group, Donna and the Dynamos. Meanwhile, Sophie secretly invites the three guys (Pierce Brosnan, Colin Firth and Stellan Skarsgard) who may or may not be her father.
