Jennifer Lawrence and the Role That Keeps Revealing Itself Bradley Cooper was home, luxuriating in bed, when he got the news of his Globes nomination, and Jennifer Lawrence, his co-star in "Silver Linings Playbook," was in Hawaii. Tough life. Actually, Ms. Lawrence was in Hawaii to shoot the sequel to "Hunger Games," the franchise that has put her on the map as a star - and a top-grossing action heroine. In the much smaller "Silver Linings," she plays Tiffany, a young widow struggling with rebuilding her relationships. It was a part she said she continued to unpack even as she was playing it, and long after, as she talks about the film on the awards circuit. "You always learn more about the character through what other people ask," she said. Because I'm not that smart. Most of the time, it's things I didn't even really think about, in that moment when you did this or that, you don't even remember. She likes the feedback. "You get to see a million different colors of your character in this movie that you made that was kind of set in stone," she said. The film involves a highly-choreographed dance number, and Mr. Cooper seemed game to reprise it, if an awards show producer asked. Ms. Lawrence, not so much. "I'm sweating, for you saying that," she said. I don't know if I ever should be dancing without lots and lots of editing. Among the 100 or so excited text messages on her phone, she had exchanged a few with film's screenwriter and director, David O. Russell. But the two of them being who they are - naturally comic - they were not traditional congrats. "I texted him a picture of a really fat pug, " she said. It was this one. Mr. Cooper was excited to be nominated in the same season as Daniel Day-Lewis and hoped to meet him. Ms. Lawrence, meanwhile, is obsessed with Bill Murray. She encountered him once, at the Critics' Choice awards, but was too nervous to say hello. "So I just stared at him awkwardly, as I'll continue to do every time I see him at these functions," she said. He's gonna start asking if that creepy girl is gonna be there again, staring at me. Mr. Murray is a Globes nominee for "Hyde Park on Hudson," so Ms. Lawrence was busy coming up with a plan of attack, in case she did encounter him. "I'm gonna go on his IMDB and look up the fun facts about him and just conversationally bring them up," she said. That's always a cool thing to do.
