Stewart, 22, and Lawrence, 21, are eyeing the role of Peyton Loftis in an adaptation of William Styron's edgy first novel 'Lie Down in Darkness', reported New York Post online.
"I want to play Peyton more than anything I can possibly taste or touch in my life. I want to play her so bad. There's a script adaptation. And it's good," Stewart said.
Whereas, Lawrence said she is obsessed with the character and feels no one would do justice to the role other than her.
"I am obsessed with that part. I have this feeling of protectiveness over characters I want to play. If someone else gets the part, I'm afraid they won't do it right. I'm trying to write the director... To convince him that I should be in his movie. I'll chase him if I have to. I'll sit outside his house," she said.
