When we first meet Johanna Mason, a ferocious, ax-wielding victor from District 7, it's on an elevator with Haymitch, Katniss and Peeta. She stares down the trio and proceeds to strip naked. "It's one of the best introductions to a character ever," says 28-year-old actress Jena Malone (Donnie Darko). "I had to learn how to do a striptease in four seconds."
For Malone, Johanna defies expectations for women in genre films. "She's not just another badass sexy female," she says. "Her sexuality is a weapon. Her humor is a weapon. They're part of her process of coping with the fact that she killed all her friends in her own Hunger Games." Malone can't shake one particular scene in which her entire body is drenched in blood. "I felt like this gladiator," she says. "The cameras would cut and I would still have this crazy energy surging through me. Johanna took over."
