During a talk with Yahoo Movies, Bryan Singer suggested that a potential crossover film with the X-Men and Fantastic Four is possible.
On conversations with Fantastic Four producers on a crossover: “Those ideas are in play. That would be a natural match-up because they’re both ensemble films and there is a natural mechanism by which to do it. It deals with time. That’s all I’m going to say.”
On the crossover being dependent on current Fantastic Four and X-Men: Apocalypse films success: “We’ll have to see how the films turn out. To just say you’re going to do it would be a mistake, you have to see how the films evolve before you make that decision to completely commit to that.”
This obviously would be a dream match-up for comic fans everywhere. We will keep an eye on the box office when these next films hit theaters. You would imagine both films would need to perform similarly for this scenario to come to fruition.
