Lawrence said she prepared for her role by "running, free running, climbing, hand-on-hand combat and yoga."
"She's a dream woman," the actress said of Katniss. "She's a female hero that doesn't even try to be a hero."
When he first got a call about playing Cinna, Katniss' über-cool stylist, he didn't know the story of The Hunger Games. But after reading the book, he knew immediately he "would love to be a part of this."
Besides being thrilled to work with Lawrence, a close friend of his daughter Zoë, Kravitz was "relieved" to find out his character wasn't as over-the-top as most Capitol residents. "I think a lot of people expected Cinna to be more flamboyant," he said. "But Gary [Ross, the director] and I discussed the character and thought it'd be more interesting to portray him like a Yves Saint Laurent or a Tom Ford—someone more classic."
Still, Kravitz didn't escape the makeup chair completely. "[Cinna] has his gold eye shadow, which is his signature," the actor said. "But [it's] his creations that are very big and over the top."
Plus, find out why Elizabeth Banks jumped at the chance to play a villain and how she portrayed Effie Trinket as "funny, tinged with a little bit of evil."
