More details about Mamma Mia 3

Mamma Mia’s glitter-soaked universe is slowly warming up for another round, and the tease for Mamma Mia 3 is getting kind of delicious. For years, producer Judy Craymer has hinted that the musical series was always meant to form a trilogy. Back in 2020, she told the Daily Mail that a third movie was part of the long game and that Universal Pictures was already on board. Now, in May 2025, she has doubled down while speaking with Deadline and confirmed that the next chapter is in active development.

Seyfried also talked about what could happen in Mamma Mia 3 as she told ET,

“I just know the three dads are going to come back, and we still won’t know who the dad is because it doesn’t matter. Meryl [Streep] is a ghost, obviously, so she’ll be around. And Julie [Walters] and Christine [Baranski] will be back singing and looking hot and we’re all going to be somewhere tropical. And ABBA will be playing.”

Universal has not announced a release date yet, so fans are left waiting. Until then, the first two films will keep viewers dancing in their living rooms and dreaming about one more round of sunshine, sequins, and ABBA magic.
