X-Men: Apocalypse star Olivia Munn revealed some frustrations she experienced on the set of the 2016 superhero film. Specifically, Munn was irked at the fact that director Bryan Singer and screenwriter Simon Kinberg apparently didn't know a great deal about her Marvel character, Psylocke.
While participating in an "Actually Me" video for GQ, Munn was asked on social media if she was frightened by how "crazy" some fans get over film adaptations of comic books. She replied, "No, because I get like that too."
"I think that people wouldn't get so crazy if it was just a really great movie," Munn continued. "When I was doing X-Men, I was actually surprised that the director [Singer] and the writer [Kinberg] didn't even know that Psylocke had a twin brother. And I had to talk to them about a lot of different things about Psylocke and some other parts of the world that they didn't know and that, as a fan, was very frustrating."
In the events of the film, Munn's Psylocke serves as a bodyguard to Tómas Lemarquis' Caliban before being recruited by Oscar Isaac's Apocalypse as one of the villain's "Four Horsemen" alongside Magneto, Angel and Storm. The X-Men ultimately defeat Apocalypse, with Psylocke escaping amidst the chaos. The character did not return for Dark Phoenix.
If Munn's comments are anything to go on, it appears the actress wasn't particularly happy with how things played out for Psylocke was portrayed in Apocalypse. Notably, she has also had a role in the Marvel Cinematic Universe, appearing as reporter Chess Roberts in Iron Man 2 (a fact she also references in the video.)
