A newly released "X-Men: Apocalypse" featurette follows James McAvoy's transformation into Professor X, as he shaves his head to properly sport the iconic hair-free look.

Thankfully, he has director Bryan Singer and his "Days of Future Past" co-star Patrick Stewart (on the phone) to lend their support throughout the process.

Worshiped as a god since the dawn of civilization, the immortal Apocalypse (Oscar Isaac) becomes the first and most powerful mutant. Awakening after thousands of years, he recruits the disheartened Magneto (Michael Fassbender) and other mutants to create a new world order. As the fate of the Earth hangs in the balance, Professor X (James McAvoy) and Raven (Jennifer Lawrence) lead a team of young X-Men to stop their seemingly invincible nemesis from destroying mankind.
