Christine Baranski is presumably rather busy with CBS All Access’ The Good Fight, and Dominic Cooper, who played Sophie’s fiancee, is starring in AMC’s Preacher.
Amanda Seyfried is the third actor announced to reprise their role in Mamma Mia: Here We Go Again!.
She joins franchise leads Meryl Streep, Pierce Brosnan, and Colin Firth in the already anticipated sequel.
These four help cover many of the sequel’s bases, but it should be interesting to see if the rest of the cast returns as well.
