McAvoy aimed for different, and not bald, portrayal of Professor X

James McAvoy has said he tried to play Professor X as differently as possible from Patrick Stewart's portrayal in the original three X Men movies.

The 31-year-old actor - who is playing a younger version of the 'X Men' character in the prequel 'X-Men: First Class' – says he felt "liberated" when studio bosses told him not to shave his head to look like Patrick's version of the professor and saw it as free reign to act the part differently.
