X-Men: Apocalypse director Bryan Singer recently revealed some interesting details about the film while talking about its first trailer that released this week. In his latest interview, Singer teased the end of the film will features an all-out battle with the super villain Apocalypse.

"The end of the movie becomes an all-out battle with a force that's very formidable. He's a hard man to break, Apocalypse. It's why he thinks he's God," Singer told Empire magazine.

Talking about the popular comic book villain's transcendent abilities, Singer said: "It's part of the mythology of Apocalypse's size, but I couldn't go full Stay-Puft Marshmallow Man where he's just Giant Apocalypse, swatting at things. I did something a little interesting in how I addressed the size thing, but I think the audience will get a kick out of it."

With Apocalypse playing the main antagonist in the movie, fans might be wondering if Magneto (Michael Fassbender) gets relegated to the sidelines in this one. However, Singer made it clear that he's as important as ever. "He's one of the most pivotal characters. Fassbender really delivers here in non-traditional comic book style. There are scenes here you will not see in any other comic book movie. I really think Erik goes through one of the most complex journeys in the movie," the director said.

X-Men: Apocalypse is slated to release on 27 May 2016. Check out the film's trailer below:
