Marvel Studios has reportedly cast Samara Weaving as Emma Frost in its forthcoming MCU X-Men film, one of the first confirmed casting moves for the reboot. The decision matters because it signals that Marvel’s long-awaited new X-Men team is beginning to take shape ahead of its planned post-Secret Wars direction.

Director Jake Schreier and Marvel chief Kevin Feige reportedly considered several candidates, while auditions for multiple roles have been under way since May. Emma Frost is a telepath who can assume a nearly indestructible diamond form; it remains unclear whether this version will be a villain or an X-Men ally. Marvel has not announced a release date or further cast members, though it is reportedly seeking younger actors to control costs.
