Director Bryan Singer posted the news on Instagram on Monday.
Psylocke made her first appearance in the comicbooks in 1976, but hasn’t had a large presence in the films. The mutant’s only movie appearance was in 2006’s “X-Men: The Last Stand,” where she served as one of the minor villains following Magneto and was played by Mei Melançon. Psylocke’s powers have been altered a few times, but they include telepathy and telekinesis.
Munn joins previously announced newcomer Lana Condor, who’s playing Jubilee, as well as returning stars James McAvoy, Michael Fassbender, Nicholas Hoult and Rose Byrne. Oscar Isaac and Kodi Smit-McPhee are also set to join the franchise.
Munn recently starred alongside Johnny Depp in “Mortdecai,” as well as last year’s “Deliver Us From Evil.” She’s currently filming “Ride Along 2,” starring Ice Cube and Kevin Hart, which will bow early next year.
Ian McKellen and Patrick Stewart, who played Magneto and Professor X, respectively, will not be returning for the next installment. “Apocalypse” will be Jennifer Lawrence’s last appearance as Mystique, she recently confirmed.
Singer is directing the film from a script by Simon Kinberg, Dan Harris and Michael Dougherty.
“X-Men: Apocalypse” is set to bow on May 27, 2016.
Munn is repped by CAA and Atlas Artists.
