Does this include a movie that isn't titled "X-Men"? Like "The Mutants" or "X-Force"? What about a movie about a specific X-Man, like a Jean Grey solo film?

@ZaneMiller - Title doesn’t have to contain “X-Men” but I will only count movies that contain multiple main characters that are or were considered a member of the X-Men team or come together in the film as the X-Men team.

See historical list of X-Men members: https://en.m.wikipedia.org/wiki/List_of_X-Men_members

Unless the characters include classic X-Men team members, I won’t count movies that focus on solo characters or teams that are only affiliated or associated with the X-Men such as Deadpool, The New Mutants or X-Force.
