There are so many directions the trilogy could head in. Obviously, at its heart, Mamma Mia! isn’t just a love story, it’s also a mother-daughter story — albeit one that took a twist in the sequel. Now that Amanda Seyfried’s Sophie is a mom herself, it could be interesting to see how that new relationship plays into any future storylines. Maybe her son will be the next to have a whirlwind romance to the tunes of ABBA’s sweetest love songs.
