It has also inspired two record-breaking films: Mamma Mia! The Movie (2008), which became the highest-grossing live-action musical film of all time, and Mamma Mia! Here We Go Again (2018), the most successful live musical movie sequel ever.

Both starred Meryl Streep, Christine Baranski, Julie Walters, Pierce Brosnan, Colin Firth, Stellan Skarsgård, Amanda Seyfried and Dominic Cooper, with Lily James, Andy Garcia and Cher joining them in the second film.
