X-Men: Apocalypse
Apocalypse and his followers will be looking to cleanse the world of humans so he can rule instead 20th Century Fox

Deadpool's massive box office success has encouraged Marvel to announce a sequel to the superhero comedy movie. X-Men Apocalypse, on the other hand, has generated immense curiosity among fans and is expected to rake in high earnings for 20th Century Fox. Though both the movies tell the story of the mutants in their own way, speculation is high about a crossover of the two different worlds from the Marvel Cinematic Universe.

Bryan Singer, who directed Apocalypse, thinks that a crossover between the ever-serious mutants from X-Men and the not-so-sober Wade Wilson is possible but the storytelling would be risky.

"If you take a character as irreverent and meta as Deadpool and connect him to something as grounded and serious as X-Men, you have to do it carefully and gently. When you drop them all in together it can be a disaster. That has to be done delicately, but there's plenty of room to do it," he told Variety.

In the Deadpool movie, there is mention of the X-mansion and Professor Xavier by the two X-Men members Colossus and Negasonic Teenage Warhead when they plan to summon Wade to join the squad. But that does not happen and an intersect between the two very different schools of thought could be interesting to watch.

However, the main challenge to tone down Wade and his alter ego Deadpool, who works contrary to the ethics of the X-Men school, remains. Besides, any character joining Professor X's squad will need to be trained meticulously.

"I think the underbelly [could be explored]. There's always something interesting about a school that's got a military aspect beneath its classrooms. Is there another layer to all of that? Is there another layer to the Hellfire Club? The idea of, 'Who's running the world?' — that's something that was touched upon in 'First Class' but has yet to be fully explored. It just has to be explored in a very gentle, methodical way. And I've seen it go haywire. I'm not going to be specific where I believe it has. The audience will tell you. But when it's done right, it all can connect."

X-Men Apocalypse premieres on 27 May in the US.
