"I dare you to show me one person who doesn't want a third Mamma Mia!" added Seyfried. Dominic Cooper, who starred as Sophie's fiance Sky in the franchise, said he often pesters producer Judy Craymer about a third movie in the franchise. "I text Judy every other day, 'Number three when?'. I know we're all dying to do it, and Meryl was definitely bummed about not being in much of the second one. She understood that was where the story goes, but I remember her saying, 'Well, I didn't wanna be dead'," Cooper said. While the first film was directed by Phyllida Lloyd, the follow-up was helmed by Ol Parker. The Mamma Mia! films also starred Christine Baranski and Julie Walters.
