9. Jennifer Lawrence. Some of you may remember Jennifer Lawrence from her highly praised role in 2010's Winter's Bone. Jennifer was all over the place in 2011 with roles in indie darlings Like Crazy and The Beaver, and her role as Mystique in the blockbuster hit X-Men: First Class. Jennifer really turned heads this year when it was announced she was cast in The Hunger Games in the coveted role of Katniss Everdeen. You can expect to see much more of Jennifer in 2012 and beyond as her star continues to rise.
