HeatVision ups the original announcement of Matthew Vaughn directing the sequel to X-Men First Class. They confirm the entire cast of the original film are returning, even high profiled actors Michael Fassbender and Jennifer Lawrence. Fassbender will be shooting the indie period drama 12 Years A Slave with director Steve McQueen (Shame, Hunger) this summer. Jennifer Lawrence who leads the Hunger Games franchise is expected to start production on the sequel Catching Fire sometime soon as well. It's really the first time we've heard that Lawrence is indeed coming back to play Raven/Mystique.
