Speaking to CBR, Chung revealed that she's been a fan of comic, particularly Marvel Comics, since she was a child. She has a special fondness for the X-Men, and, though there are plenty of female mutants she'd be happy to play in a future film, there's one that stands out from the rest.
Oh, I mean come on! As a kid, Marvel Comics was the only thing that I collected with my sister. We loved it so much that we -- in terms of taking care of the comic books, we never wanted to read them, we just kept them in their plastic sleeves. If we wanted to read one special one... Remember when Superman died, they sold -- well, that's DC, I know! -- but in terms of comic books, whenever they were sealed from the manufacturer, we would buy two, one to read and one to keep in the sleeve. But growing up, "X-Men" was my favorite Marvel property. It was Wolverine and Cyclops. I've always wanted to play a Jubilee or a Storm or a Jean Grey, the Phoenix series was amazing, and I was so intrigued with Mystique. But ultimately I thought the coolest character was Psylocke. I really wanted to be Psylocke… Hopefully they'll bring her into something. But I think the fans -- I kind of put it out in the universe, and the fans, some are like, "Oh my God, that would be amazing." And the other fans are like, "No, that's so wrong casting. She needs to be British. She needs to be this and that!" And so I just put it out there for fun
Chung even showed that she's been keeping her British accent in form, in case they decide that's needed for the character.
Chung may yet get her wish. X-Men: Apocalypse writer/producer Simon Kinberg has previously said that Psylocke is one of several characters he'd like to include in the film.
X-Men: Apocalypse will be released May 27, 2016.
