Please reincarnate Meryl Streep and Stellan Skarsgård for Mamma Mia 3
Although Streep's character is dead and Skarsgård says he'll be dead, both actors would gladly find a way to reanimate themselves for a Mamma Mia threequel

In Mamma Mia!’s magical version of Greece, anyone can burst out in joyful song at any moment, a young woman can squat in a broken-down hovel and miraculously turn it into the most beautiful resort you’ve ever seen, and blonde Cher can just pop up wherever and whenever she wants. In this literal Garden of Eden, why wouldn’t a beloved mother and grandmother come back from the dead? It makes perfect sense to us, but more importantly, it makes perfect sense to the late, great Donna Sheridan herself.
“I’ll have to schedule a knee scoping before we film, but if there’s an idea that excites me, I’m totally there. I told [producer Judy Craymer] if she could figure out a way to reincarnate Donna, I’m into that,” Meryl Streep said of her potential triumphant return in a speculative Mamma Mia! 3. This comes via a long Vogue oral history of the original film, in which she also suggested that “it could be like in one of those soap operas where Donna comes back and reveals it was really her twin sister that died.”
