Trivia: All of the entire cast performed their own singing.
Trivia: While neither the stage show nor the film reveals who Sophie's real father is, there is an official answer. According to Catherine Johnson and Phyllida Lloyd, Sophie's real father is Bill. Bill's character was Australian in the original stage production, but in the film he became a Swede instead, and he's played by Swedish actor Stellan Skarsgård. This means the film's Sophie has her roots in Sweden - just like "Mamma Mia!"
Trivia: Rosie's cookbook that is mentioned in the beginning of the movie is a bit of an inside joke and refers to "Calendar Girls" that Julie Walters starred in.
Chosen answer: Meryl Streep and Pierce Brosnan got married because they loved each other and had done for many years. The daughter changed her mind about getting married because she realised what really mattered to her and that seeing the world while they were young and free wasn't such a bad idea after all, that she didn't need to get married and hang around for her mother's sake.
