Why Sydney Sweeney & Sabrina Carpenter?
According to Seyfried, both actresses bring something unique:
Sydney Sweeney has proven herself in both drama and comedy, and Seyfried thinks her emotional depth and comedic timing would blend perfectly with the series’ over-the-top charm.
Sabrina Carpenter, whose music career is soaring, represents the exact kind of musical star power that could elevate the film’s soundtrack and youthful appeal.
Seyfried reportedly praised Carpenter’s stage presence and vocal ability, imagining how her voice would shine in ABBA classics. Meanwhile, she sees Sweeney as a natural fit for the franchise’s heartfelt storytelling and chaotic family dynamics.
What This Means for Mamma Mia! 3
