Jennifer Lawrence, the insanely attractive 19-year-old star of the award-winning indie-drama Winter’s Bone, has been cast in Mathew Vaughn’s eagerly anticipated X-Men origins reboot X-Men: First Class. Lawrence will play sexy shape-shifting mutant Mystique (played by Rebecca Romijn in the original X-Men trilogy).

Lawrence joins a cast that includes Alice Eve as Emma Frost, Nicholas Hoult as Beast, Caleb Landry as Banshee, Michael Fassbender as Magneto and James McAvoy as Prof. Charles Xavier. Kevin Bacon has also signed on to star as the film’s villain (possibly Mister Sinister according to internet rumors).

X-Men: First Class will go into production next month in London. Twentieth Century Fox has scheduled the film for release on June 3, 2011.

Lawrence is also set to headline A Bigger Boat’s new frightener House at the End of the Street. She plays a teen girl caught up with a boy whose family was murdered.
