Mamma Mia! 3 has gotten a majorly optimistic update from one of its primary producers. The original 2008 smash hit movie Mamma Mia! was based on the jukebox musical of the same name, which used music from the ABBA songbook to bring to life the story of Sophie, a young woman who invites her three possible fathers to her wedding unbeknownst to her mother Donna. In 2018, the sequel Mamma Mia! Here We Go Again paralleled flashbacks to Donna's time as a college graduate and expectant mother with scenes from Sophie's present-day life.
