Production continues on 20th Century Fox’s summer 2016 mutant ensemble, X-Men: Apocalypse, and director Bryan Singer has taken to Instagram to reveal an event that has been long in the making since James McAvoy was cast as Charles Xavier in X-Men: First Class: the character’s traditional bald head. Check it out in the gallery below!

McAvoy leads a cast for the film that also includes Michael Fassbender, Jennifer Lawrence, and Nicholas Hoult along with the return of Rose Byrne as Moira MacTaggert, Evan Peters as Quicksilver, Lucas Till as Havok and newcomers Alexandra Shipp as Storm, Ben Hardy as Angel, Tye Sheridan as Cyclops, Sophie Turner as Jean Grey, Lana Condor as Jubilee G, and Olivia Munn as Psylocke. Oscar Isaac is starring as the film’s title antagonist with Simon Kinberg scripting from a treatment by Mike Dougherty, Dan Harris and Kinberg.

Said to be the conclusion of a trilogy started with X-Men: First Class and continued with X-Men: Days of Future Past, the Bryan Singer directed X-Men: Apocalypse is set for release on May 27, 2016.
