Producer-screenwriter Simon Kinberg says actress Rose Byrne will reprise her X-Men: First Class role as Moira MacTaggert in the forthcoming X-Men: Apocalypse. Byrne's CIA agent character sat out X-Men: Days of Future Past, meaning it will be roughly twenty years since Moira last encountered the X-Men when she appears in the 1980s-set Apocalypse. “She’s a significant character in the movie,” Kinberg told Entertainment Weekly.
