Mamma Mia 3 Confirmed by Amanda Seyfried as Casting Wishes Take Center Stage
Amanda Seyfried has confidently stated that a third Mamma Mia film is moving forward. The actress revealed she believes the project is a “done deal.” Her comments follow producer Rita Wilson’s recent hints about the musical’s future.
This unofficial confirmation has sparked excitement among fans of the ABBA-filled franchise. Seyfried also shared her vision for the plot and potential new cast members.

Sophie’s Future and a Star-Studded Wishlist
According to Entertainment Tonight, Seyfried is eager to explore her character’s motherhood journey. She expressed a desire to see Sophie with children in the new story. This evolution would provide a fresh narrative for the beloved character.
The actress has publicly suggested two popular stars for key roles. She named Sabrina Carpenter and Sydney Sweeney as her top choices. Seyfried proposed Carpenter could play a long-lost cousin, while Sweeney could join the ensemble.
She enthusiastically endorsed the idea of new talent joining the established cast. Seyfried noted many young actresses are interested in being part of the project. She fully supports expanding the Mamma Mia family with fresh faces.
Plot Speculations and Returning Favorites
Seyfried offered intriguing details about the potential storyline during her interview. She predicted the return of all three fathers from the original films. The central mystery of Sophie’s paternity would remain humorously unresolved.
The actress addressed Meryl Streep’s character Donna Sheridan, who died in the second film. Seyfried suggested Streep would appear as a ghostly presence. This approach would allow the Oscar-winner to participate despite her character’s fate.
She confirmed that Julie Walters and Christine Baranski would reprise their roles. Seyfried imagined them returning “singing and looking hot” in a tropical location. The essential ABBA soundtrack would naturally feature throughout the film.
The potential Mamma Mia 3 continues to generate significant audience anticipation as casting discussions evolve. With Seyfried’s confident announcement and creative suggestions, the project appears closer to reality than ever before.
