Jennifer Lawrence. She is set to play the blue skinned character in Matthew Vaughn's X-Men: First Class. I don't know her work first-hand, but to be honest, I was so biased AGAINST Heard, this will do just fine for me.
And as rumored, Kevin Bacon is confirmed as the villain in the movie. Still no word on what character he'll be playing, but I still think it's Sinestro. Love it!
