An actress who relies on her instincts on how to read a character and make her real, Jennifer Lawrence earned stardom with her Oscar-nominated role in “Winter’s Bone” and iconic action heroine Katniss Everdeen in “The Hunger Games.” But she came into her own (and won the Oscar) in David O. Russell’s unsentimental romance “Silver Linings Playbook.” In this delicately edited relationship comedy, she and Bradley Cooper play two lost, emotionally damaged yet attractive people who find comfort and kinship. We root for them to heal each other, win their dance contest and make their families happy ever after. —AT
