X-MEN: DAYS OF FUTURE PAST: First Look at Professor X

James McAvoy is now filming scenes on the set of Bryan Singer‘s X-Men: Days of Future Past and the director has shared the first look at the 70’s fashion that Charles Xavier will be sporting this time around, via his Twitter account.

Singer commented on the photo with just the word “Serpico,” most probably referencing the 1973 Sidney Lumet film, which starred Al Pacino as NYPD officer Frank Serpico. Check it out below!

The film is based on the comic book storyline ‘Days of Future Past’, which ran in Uncanny X-Men #141 and 142 back in 1981 during Chris Claremont and John Byrne’s run and introduced the idea of an alternate future for Marvel’s mutants that grew out of the Brotherhood of Evil Mutants killing an important senator, leading to a future where all mutants are hunted by Sentinels.

Reprising his role from X-Men: First Class, McAvoy joins the star cast along with Ian McKellen, Patrick Stewart, Hugh Jackman, Jennifer Lawrence, Michael Fassbender, Nicholas Hoult, Anna Paquin, Ellen Page, Shawn Ashmore, Peter Dinklage, Omar Sy, Halle Berry, Daniel Cudmore, Fan Bingbing and Boo Boo Stewart. X-Men: The Days of Future Past is set for July 18th, 2014 release.
