The MPAA gave X-men: Days of Future Past a PG-13 rating due to the violence and nudity, and this scene may be one reason why. In the latest clip, only the second official one released by 20th Century Fox, Jennifer Lawrence's Mystique makes a bold attack against Bolivar Trask (Peter Dinklage), the creator of the mutant-hunting Sentinels. She uses her shape-shifting powers to hide in plain sight, but once discovered she reverts to form and is naked as a jaybird; a scaly blue jaybird but nude nonetheless.
X-men: Days of Future Past is directed by Bryan Singer and opens May 23rd.
