James McAvoy is finally transforming for his role as Young Professor X.
The change comes for the upcoming "X-Men: Apocalypse," a prequel that features young versions of Storm, Cyclops, Jean Grey and Nightcrawler.
According to a new Instagram photo, McAvoy is channeling Patrick Stewart's iconic rendering of Professor X -- aka finally losing his hair -- for his newest portrayal of the character.
Squint and you might almost think it's a young Stewart in the chair.
