Lily James and Meryl Streep as Donna
Mamma Mia! Here We Go Again comes out on July 20, and we're so excited to be reunited with the gang. While the movie will serve as a sequel to the 2008 film 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), there are also a few dashing young men playing Sophie's potential fathers. See the original cast members and their younger selves side by side ahead.
