MTV: ''Well, actually only half of Beast has been revealed. "X-Men: Days of Future Past" director Bryan Singer has tweeted a picture of the Beast, and we assume that's returning star Nicholas Hoult underneath the blue fur. Hoult is reprising the role that he took on in "X-Men: First Class," and he's one of only four actors from that first film to return.
Singer included a passage from Jeanne Marie Le Prince de Beaumont's Beauty and the Beast in the tweet. Check out the full picture below. As far as first looks go, this one is pretty awesome.''
