Mamma Mia! (promoted as Mamma Mia! The Movie) is a 2008 romantic comedy film containing music directed by Phyllida Lloyd and written by Catherine Johnson based on her book of the 1999 theatre show of the same name. The film, in turn, is based on the songs of pop group ABBA, with additional music composed by ABBA member Benny Andersson. The film features an ensemble cast, including Christine Baranski, Pierce Brosnan, Dominic Cooper, Colin Firth, Amanda Seyfried, Stellan Skarsgård, Meryl Streep and Julie Walters. The plot follows a young bride-to-be who invites three men to her upcoming wedding, each one with the possibility of being her father. The film was an international co-production between Germany, the United Kingdom, and the United States, and was co-produced by Playtone and Littlestar Productions.
Principal photography primarily took place on the island of Skopelos, Greece from August to September 2007. The film was distributed by Universal Pictures. Mamma Mia! held its world premiere on June 30, 2008 at Leicester Square in London and premiered on July 4, 2008 in Stockholm, Sweden, with Andersson, Björn Ulvaeus, Anni-Frid Lyngstad and Agnetha Fältskog in attendance. The film was released theatrically on July 10 in the United Kingdom, on July 17 in Germany and on July 18 in the United States. It received mixed reviews from critics, who praised the musical numbers and production values, but criticized the plot and casting of inexperienced singers, in particular Brosnan and Skarsgård. Nonetheless, the film was popular with audiences and grossed $615 million worldwide on a $52 million budget, becoming the fifth highest-grossing film of 2008. A sequel, titled Mamma Mia! Here We Go Again, was released on July 20, 2018 with most of the main cast returning.
