Millions of fans have eagerly been awaiting the release of The Hunger Games, but Jennifer Lawrence could have gone a bit longer without seeing herself as heroine Katniss Everdeen.
"I am a troll," she joked on The Late Show with David Letterman Tuesday. "I hate myself. I think the movie is great, but their biggest mistake was [casting] me."

The 21-year-old Academy Award nominee said she's still getting used to life in the spotlight. "Out of the four premieres, I've tripped in two or three of them. Like, massive trips," she laughed. "It's so scary and then I end up getting so nervous that I get really hyper. So then I go do interviews and I'm like, 'I'm like a Chihuahua. I'm shaking. I'm peeing!' And then afterwards I'm like, 'I just talked about peeing on the red carpet!'"
Though The Hunger Games movie — based on the popular trilogy by author Suzanne Collins — is a guaranteed hit, Lawrence said she didn't join the franchise to become a household name.
"I've never really paid attention to the box office or how much money any film makes before," Lawrence told host David Letterman, 64. "This one, people keep reminding me, so now it's there, but it's not something I normally care about."
