“I think in some ways, it's the biggest X-Men film we've done, both in terms of the external stakes -- we've never done one of these before where there's an extinction-level event for the whole world -- and I think it's the biggest emotionally, too. Because the situation is so heightened, the dynamic between the main characters is as heightened and intense as it's ever been.”
