James McAvoy is sporting a dramatically different look as young Professor Xavier in "X-Men: Days of Future Past."
Instead of his dapper, well-groomed appearance in "First Class," the young paraplegic telepathic mutant looks like a cast member of "That 70s Show" in an image director Bryan Singer tweeted from the set.
"Serpico," Singer wrote with the pic, suggesting Prof. X happily went through a hippy phase, circa 1973, before becoming the bald and studious Marvel mutant movie audiences were introduced to in the year 2000's "X-Men."
Patrick Stewart, who previously starred in three installments of the franchise, will return as the older Xavier when "Days of Future Past" hits theaters on July 18, 2014.
Here's the psychadelic pic:
