Kristen Stewart wants an evil role

London: Actress Kristen Stewart wants to take on an evil role.

The actress says she would love to play the role of psychotic Cathy Ames from ‘East of Eden’.

"She`s a psychopathic, evil ****! I haven`t done that yet," quoted her as saying.

Stewart also has a burning desire to star in a film version of William Styron`s 1951 book ‘Lie Down in Darkness’.

She admits that playing Peyton Loftis, a suicidal girl who lives with her dysfunctional family in Virginia, would be ideal.

"I want to play Peyton more than anything I can possibly taste or touch in my life. I want to play her so bad," she said.
