“Extra’s” Terri Seymour sat down with Michael Fassbender and James McAvoy as they promoted “Dark Phoenix.”

Michael and James raved about their co-star Sophie Turner, who is the lead of the film and a "Game of Thrones" star. While James revealed he has “a complicated relationship” with “Game of Thrones,” he said, “Sophie has absolutely nailed it. It’s been incredible watching her.”

Fassbender said he hasn’t watched any of the show, but plans to binge-watch it since all the episodes are available. Watch!
