Now while these films are not specifically X-Men releated films it can only be assumed. Some films in development include X-Force, Deadpool 3, Gambit and an X-23 film. However, it’s very possible that the studio will once again attempt to get another Fantastic Four film off the ground to eventually crossover with their main X-Men universe films.
