Lily James to Play a Young Meryl Streep in “Mamma Mia!” Sequel
Baby Driver actor Lily James will be playing a young Donna in the sequel via flashbacks, the character whom Meryl Streep played in the original film and will reprise in the sequel as well.
Amanda Seyfried is set to reprise her lead role and Meryl Streep is also expected to return, albeit in a much smaller capacity. Insiders tell us the story will focus on Sophie (Seyfried) in the present and Donna (Streep) in the past. 
The story is being kept under wraps but could potentially focus on events surrounding Streep, Firth, and Brosnan’s characters prior to the original film.
