Lawrence has just been named as the leading lady in the eagerly anticipated Hunger Games, based on the best-selling book by Suzanne Collins.
Taking on the part of Katniss Everdeen, a fierce and feisty heroine competing in the ultimate game of life-or-death, Lawrence, 20, has extraterrestrial inspiration for tapping into the 'fighting spirit' of her character.
She told Entertainment Weekly: “Sigourney Weaver's Ripley in Alien is the first movie that comes to mind.”
And while she may not be kicking alien butt in the adaptation, Lawrence knows one thing - there's a lot of fans that will want to kick her butt if she doesn't deliver.
Lawrence added: “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's masterpiece.'
