In the past few years, a multitude of superhero characters have been adapated on the silver screen. While some of them failed to impress comic book fans, there is no denying that most theatrical releases, whether based on characters from DC or Marvel, have been relative box-office hits.

Because of the success of the adaptations, it comes as no surprise that another "X-Men" installment is rumored to be in the works. However, this time, it is shaping up to be more interesting as the movie is speculated to be tied into "Fantastic Four."

Last year, in an interview with ComicBook.com, "X-Men" writer and producer, Simon Kinberg, spoke about the probability of having an "X-Men" and "Fantastic Four" crossover, much to the excitement of both franchises' fans.

"I love the characters, I love the characters in Fan Four, and I love the new cast. Obviously I love the characters and cast of X-Men. So, hypothetically, the notion of putting them together is really intriguing, and there's some really fun stuff that the comics have done in the past. So it's not out of the realm of possibility," exclaimed Kinberg.

While Bryan Singer is not opposed to the idea, the director of "X-Men" has explained in an interview with Variety that he would only attach his name to the crossover if "X-Men" and "Fantastic Four" would be successful.

"We have to see how the films turn out — how this film turns out, how 'Fantastic Four' plays, to really understand what kind of desire and how that would really work. I think to just say you're gonna do it is a mistake. You have to see how the films evolve before you make the decision to completely commit to that."

The reboot of "Fantastic Four" starring Miles Teller, Kate Mara, Michael B. Jordan, and Tony Kebbell will be released on Aug. 7, 2015.

On the other hand, "X-Men: Apocalypse" will hit the big screen on May 27, 2016.
