One of the fun things about Bryan Singer’s X-Men prequel movies is the interesting fashion that we’ve seen the group of fledgling mutants sporting as they move through the decades. Next up in X-Men: Apocalypse is the 1980s, which will introduce young versions of Storm, Cyclops, Jean Grey and Nightcrawler – whom we’ve already glimpsed in their trendy period clothing.

Professor Charles Xavier, sadly, won’t get to experiment with any crazy eighties hairstyles. He sported a sensible Oxford ‘do in X-Men: First Class and a shaggy seventies mane and beard in X-Men: Days of Future Past, but in X-Men: Apocalypse he’ll begin the transition into Patrick Stewart’s version of the character by going bald.

We know this for sure thanks to a new behind-the-scenes photo poster by Singer on Instagram, which shows actor James McAvoy in the late stages of having his head completely shaved. X-Men: Apocalypse began production a couple of weeks ago so it’s possible that Charles will have hair for at least part of the movie. For the majority of it, however, his scalp will be bared to the elements.

McAvoy first hinted that he might have to say goodbye to his locks during an interview last year, in which he said, “I’ll be older in this one. [And] I think I’m losing my hair finally.” The new look will certainly help to make the difference between his appearances in X-Men: Days of Future Past and X-Men: Apocalypse a bit more drastic; it’s not easy to make an actor look a decade older in the space of just a couple of years.

It’s difficult to say whether McAvoy looks older in this side view, but he certainly looks more severe and – more importantly – he could definitely pass for a young Patrick Stewart. In the comic books Xavier loses his hair in his teens as a side effect of his mutation, but in the film universe he will be around forty years old by the time it disappears completely. Perhaps his hairline starts receding and he decides to do the sensible thing and chop off the rest rather than watch it slowly disappear.

The screenplay for X-Men: Apocalypse was written by veteran X-Men writers Simon Kinberg, Michael Dougherty and Dan Harris. Oscar Isaac will play the new villain, Apocalypse: an ancient and immortal mutant who shows up in the 1980s to bring new trouble for Professor X and his young team of X-Men.
