Mamma Mia! Here We Go Again [1] comes out on July 20, and we're so excited to be reunited with the gang [2]. While the movie will serve as a sequel to the 2008 film [3] Mamma Mia!, it also serves as a bit of prequel as it flashes back to Donna's life before she was a mom. While Lily James will be playing a younger Donna (originally Meryl Streep [4]), there are also a few dashing young men playing Sophie's potential fathers.
