Kristen Stewart's film career is definitely on a roll.

From playing a love struck teenager in "Twilight" to a medieval kick-ass princess in "Snow White & the Huntsman," Stewart is ready to play edgier and more mature roles. In fact, Kristen says playing a suicidal c*nt seems like the perfect career move so far.

The highly-anticipated end to the "Twilight Saga: Breaking Dawn Part 2" is set for a November premiere. This is enough for "Twi-hard" fans to go on frenzy and camp out hours before the premiere. While "Twilight" may be on its end by this year, it does not necessarily mark the end of Stewarts' film career.

From going topless for a film in the Cannes Film Festival to kissing Chris Hemsworth in "Snow White," Stewart's film career proves to reaching higher and better levels. Yet, if there is one role on Stewart's mind, it would be to play a suicidal whore. The 22-year old admitted to wanting to play darker and edgier roles. In the June issue of Elle Magazine, Stewart opens up on her dream role as Peyton Loftis in the novel, "Lie Down in the Darkness".

"I want to play Peyton more than anything I can possibly taste or touch in my life. I want to play her so bad," admitted Stewart. For those who haven't heard of the book or what Kristen's role would be like, Loftis follows the story of a psychologically disturbed girl who falls in love with her own father.

"She's in love with him. I mean, I think she's in love with him," explained Stewart of her character, Peyton.

"It's not his fault. They're the most f***ed-up family." As for who is the perfect actor to play the father, the actress enthused, "[Colin] Firth would be perfect," continued Kristen.

Another role that the 22-year old beauty is eyeing would be the role of Cathy Ames in the novel, "East of Eden". Cathy is described as a murderous young woman who leaves her kids to operate a brothel. It is most definitely a dark and twisted role, yet Kristen still has her eye on it.

"She's a psychopathic, evil c**t! I haven't done that yet," explained Stewart.

Well, Stewart might have to wait a few more years before she gets to play any of those. Given Stewart is a bit busy with a few films on her hand, the roles of a psychologically disturbed teen and that of a murderous mother can wait. For now, Stewart is set to star in the dark comedy, "Cali" where she'll be playing Mya. This is one film Kristen fans should watch out for.
