Firth among the crooners for 'Mamma!'


Colin Firth, Stellan Skarsgard and Christine Baranski are joining the cast of "Mamma Mia!" -- Universal Pictures and Playtone's adaptation of the popular ABBA musical. Phyllida Lloyd is directing the musical, which is being produced by Playtone and Littlestar.

The trio join Meryl Streep, Pierce Brosnan and Amanda Seyfried in the production, which shoots from June-October in London and Greece.

The story revolves around a bride-to-be (Seyfried) and her formerly rebellious mom (Streep) who raised her on a Greek island and never disclosed the identity of her father. The bride locates three men who might be her father and invites them to her wedding. The musical features 22 ABBA songs, including "Dancing Queen," "Take a Chance on Me" and "The Winner Takes It All."

Firth is one of the three possible fathers, a British businessman. Firth previously sang, though briefly, in "The Importance of Being Earnest," but "Mamma Mia!" will be his first musical.

Skarsgard plays another possible dad. Baranski portrays a plastic surgery-loving party girl in her 40s who is bossy and boozy.

Producing are Playtone's Gary Goetzman and Littlestar's Judy Craymer. Tom Hanks, Goetzman's partner at Playtone, and Rita Wilson are executive producing along with ABBA members and songwriters Benny Andersson and Bjorn Ulvaeus.

The movie's screenplay was written by Catherine Johnson, who wrote the show's book. Holly Bario is overseeing for Universal.

Brit actor Firth may be best known to American audiences for playing Mark Darcy in the "Bridget Jones" movies. He has completed production on Anaud Tucker's "And When Did Your Last See Your Father?"; "Then She Found Me," directed by Helen Hunt; and "The Accidental Husband," opposite Uma Thurman. Firth is represented by CAA and ICM London.

Skarsgard, repped by ICM, returns as Bootstrap Bill in this summer's "Pirates of the Caribbean: At World's End."

Baranski, whose credits include the Academy Award-winning "Chicago," is repped by UTA and Viking Entertainment.
