The X-Men series remains one of the most popular superhero movie franchises, with a number of spinoff films in the works, alongside the ongoing main movies. X-Men: Apocalypse is due next summer, and is to be the final film in a series that began way back in 2000. Director Bryan Singer has spoken about what fans can expect from the movie when it arrives.

As reported by comicbookmovie.com, Singer was asked about the film while attending a screening of his classic thriller The Usual Suspects at the San Pedro International Film Festival. “It cuts a little long right now,” he said. “I think it’s gonna be a longer X-Men movie. The X-Men movies, I usually I keep under two hours, but this one I may actually let be a longer movie because it’s sort of a wrap-up of six movies. There’s even an homage at the end. There’s a scene–it’s gonna get spoiled because we decided to use it in the trailer which comes out, like six months, but it’s a really cool trailer–but the [homage] is kind of a wrap-up of six movies.”

Singer also spoke about working with Michael Fassbender, who plays the young Magneto in the film. “Fassbender did something so wonderful in this movie… We’re at the end of the scene, and he asked me not to call cut and when the scene was over, he continued and did something that made me cry. It was so beautiful, I’ve never seen an actor do this for me and [Fassbender] just took the scene to a whole other level.”

The previous X-Men movie, Days of Future Past, was released in 2014, and became the highest grossing film in the series to date, earning more than $748 million worldwide. Other X-Men related films in the works include Wolverine 3, Deadpool and Gambit.

X-Men: Apocalypse is due for release on May 27, 2016. It also stars James McAvoy, Jennifer Lawrence, Oscar Isaac, Nicholas Hoult, and Rose Byrne.
