Seyfried stars in the dark retelling of the classic "Little Red Riding Hood" fable, set in a medieval village where a werewolf has been terrorizing the citizens.
The actress has revealed she will not appear in a "Mamma Mia!" sequel because film bosses would struggle to put together a new installment.
She recently told Britain's Marie Claire magazine, "F**k no! That's never gonna happen. Like, what would they do? What would they write about? How would they get all the actors back?"
