The Snow White and the Huntsman star told Elle that playing Peyton Loftis - a suicidal girl who lives with her dysfunctional family in Virginia - is her ideal movie role.
"I want to play Peyton more than anything I can possibly taste or touch in my life. I want to play her so bad," Stewart said.
The 22-year-old added that the complicated relationship Peyton shares with her father Milton is an attraction for her.
"She's in love with him. I mean, I think she's in love with him. It's not his fault. They're the most f**ked-up family!" she explained.
Stewart added that the Lie Down in Darkness screenplay is already attracting interest from two high-profile male stars.
"There's a script adaptation I've read and it's good," she commented. "Two people vying for the part of the father are Daniel Day-Lewis and Colin Firth. Daniel would be perfect."
Stewart also expressed a desire to take on an "evil" role. The actress admitted that East of Eden's Cathy Ames is the character she'd most like to play.
"She's a psychopathic, evil c**t! I haven't done that yet," she said.
