When indie darling Jennifer Lawrence was cast as heroine Katniss Everdeen in the big-screen adaptation of Suzanne Collins' beloved novel The Hunger Games, diehard fans were none too happy. Lawrence, they said, was too old at 21 to play a 16-year-old and too curvy to portray the starved resident of the opressed Panem (a.k.a. a post-apocalyptic America ruled over by the despotic Capitol) who reluctantly volunteers to take part in vicious government-run tournament where 24 teens and tweens battle to the death on live TV. Were the naysayers right? Not so much. Lawrence trained her butt off, transformed her appearance and took archery lessons for the role -- and her dedication shows on the screen. In the film, she is "The Girl on Fire," weilding a bow just as deftly as Robin Hood and showing off her sheer physicality (and charisma) as she fights for survival in -- you guessed it -- The Hunger Games.
