Mystique Will Definitely Be Blue In X-Men: First Class

We've been hearing some strange things about X-Men: First Class. It's hard to really determine how it will turn out. It's easy to overreact and assume the worst. Maybe it's wishful thinking but I'd like to think that maybe there's some hope that it will turn out to be an entertaining movie. 
 
While we've been struggling to determine how this will fit in with the other X-Men movies (I'm pretty sure they've never officially referred to it as a 'reboot'), we could have some reassurance with how "young" Mystique will look. 
 
Jennifer Lawrence appears in W Magazine (via TotalBeauty.com) and talked about a couple of her upcoming roles. She mentioned while playing Mystique, she has to undergo 12 hours of prosthetics and that the role requires her to "be in the buff" a bit. The nice thing is she seems to have a good view on how to handle herself and Hollywood.  

My job is not to be skinny, my job is to act. The business does try to type you. You can either be pretty and dumb […]But you can't say no. I'm good at saying no. 

It's nice to hear that not all young actresses cave to the pressure that Hollywood and society often forces upon them.    
 
What role do you think Mystique will play in this X-Men story dealing with a younger Professor X and Magneto set in the 60s?
