Mamma Mia! (promoted as Mamma Mia! The Movie) is a 2008 jukebox musical romantic comedy film directed by Phyllida Lloyd and written by Catherine Johnson, based on her book from the 1999 musical of the same name. The film 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 Meryl Streep, Christine Baranski, Amanda Seyfried, Pierce Brosnan, Dominic Cooper, Colin Firth, Stellan Skarsgård, and Julie Walters. The plot follows a young bride-to-be named Sophie (Seyfried) who invites three men (Brosnan, Firth, and Skarsgård) to her upcoming wedding, with the possibility that any of them could be her real 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 ABBA members Benny Andersson, Björn Ulvaeus, Anni-Frid Lyngstad and Agnetha Fältskog in attendance. It was later theatrically released July 10 in the United Kingdom, July 17 in Germany, and July 18 in the United States. It received mixed reviews from critics, who praised the musical numbers and production values, but criticized the casting of inexperienced singers and campy tone. However, it was a box-office success, grossing $611.5 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 much of the cast returning.

Les Misérables is a 2012 epic period musical film directed by Tom Hooper from a screenplay by William Nicholson, Alain Boublil, Claude-Michel Schönberg, and Herbert Kretzmer. It is based on the stage musical of the same name by Schönberg, Boublil, and Jean-Marc Natel, which in turn is based on the 1862 novel Les Misérables by Victor Hugo. The film stars Hugh Jackman, Russell Crowe, Anne Hathaway, Eddie Redmayne, Amanda Seyfried, Helena Bonham Carter, and Sacha Baron Cohen, with Samantha Barks, Aaron Tveit, and Daniel Huttlestone in supporting roles. Set in France during the early nineteenth century, the film tells the story of Jean Valjean who, while being hunted for decades by the ruthless policeman Javert after breaking parole, agrees to care for a factory worker's daughter. The story reaches resolution against the background of the June Rebellion of 1832.

Following the release of the stage musical, a film adaptation was mired in development hell for over ten years, as the rights were passed on to several major studios, and various directors and actors considered. In 2011, the stage musical's producer Cameron Mackintosh sold the film rights to Eric Fellner, who financed the film with Tim Bevan and Debra Hayward through their production company Working Title Films. In June 2011, production of the film officially began, with Hooper hired as director. The main characters were cast later that year. Principal photography began in March 2012 and ended in June. Filming took place on locations in Greenwich, London, Chatham, Winchester, Bath, and Portsmouth, England; in Gourdon, France; and on soundstages in Pinewood Studios.
