Which makes the upcoming TV series—about Professor X’s son David, who isn’t sure if he’s crazy or if he actually does have powers—less of a spinoff and more of... well, just an X-Men show.
This shouldn’t be a huge surprise, given that there’s no way Fox would ever want to turn Patrick Stewart/James McAvoy’s Professor X into a deadbeat dad in their lucrative movies (also, the chances of the show being able to afford any of the stars of the movies, thus directly tying it into the movie continuity, were rather slim).
Speaking at the Television Critics Association 2016 winter press tour, FX president John Landgraf gave some specifics on how the universe of the show is different, especialy in regards to mutants:
It’s not in the continuity of those films in the sense the current X-Men films take place in a universe in which everybody on planet Earth is aware of the existence of mutants. The series Legion takes place in a parallel universe, if you will, in which the US government is in the early days of being aware that something called mutants exist but the public is not. I wouldn’t foresee characters moving back and forth because they really are parallel universes.
Landgraf also added the series might take place a few years in the past, which seems kind of unnecessary if this is an entirely new universe, but whatever. He also did not refute the possibility of movie mutants appearing on the show in some capacity, although he indicated that at the moment the show consists entirely of new characters.
The series hasn’t even been ordered, but Landgraf is bullish enough about the scripts that he said the show would likely premiere before the end of the year.
