The Winter's Bone star beat out fellow 2011 Oscar nominee Hailee Steinfeld and Abigail Breslin to land the lead role in Gary Ross' new drama - based on Suzanne Collins' hit book.
The casting was made official on Friday (18Mar11) when Ross confirmed he had made his pick for leading lady.
And now Lawrence has released a statement.
She writes, "I couldn’t be happier about being a part of Hunger Games and to play Katniss. I have a huge responsibility to the fans of this incredible book and I don’t take it lightly. I will give everything I have to these movies and to this role to make it worthy of Suzanne Collins' masterpiece."
And she's looking forward to the pre-film training she'll have to undertake to play all-action Everdeen: "I’ve never shot a bow and arrow, so that’ll be cool."
