Fox has done a pretty good job, as every studio does when there's a superhero movie in production, at keeping a tight lid on details from X-Men: First Class, which is currently shooting in London. They've got all the actors locked away on the set and sworn to secrecy-- all except Jennifer Lawrence, who got a brief reprieve to travel to L.A. and do a little press for Winter's Bone, the indie film that made her an instant star at Sundance earlier this year, and may very well lead her to a Best Actress nomination at this year's Oscars.

Lawrence walked the red carpet and talked to a few reporters, including Hollywood Elsewhere's Jeffrey Wells, who got her to talk a little about X-Men and the blue makeup she wears to play Mystique, a younger version of the mutant played by Rebecca Romijn in the earlier three X-Men films. Though Lawrence described an arduous process of putting goon blue makeup to become the mutant, she said that "only 10% of her screentime" will be in the full Mystique look.

Though Mystique can shift into whatever shape she likes, if only 10% of Lawrence's own screentime is in the blue makeup, that presumably means she'll spend the rest of her time looking like herself, a pretty, young blonde woman. Is this because Mystique is younger and maybe not as comfortable with her natural appearance? Or just because they didn't want to put poor Lawrence through all the makeup process again? Either way it should help distinguish her take on the character from Rebecca Romijn's, and also help build Lawrence's own star profile-- after all, you can't be famous if nobody knows what you look like without the blue makeup.
