Charlize Theron has played more than a few not-so-nice characters. She received critical acclaim for her role in "Young Adult," where she played an unstable woman intent on winning back her married high school sweetheart. Now she's working on a project with "Rise of the Planet of the Apes" director Rupert Wyatt called "Agent 13," in which she'll reportedly play another femme fatale.

When MTV News caught up with the "Snow White and the Huntsman" actress, she revealed how the sci-fi project came together.

"It's a pitch that I heard a month or so ago and I fell in love with this pitch," she said. "And ironically, at the same time, I really wanted to have a general [meeting] — 'cause you know how I stalk directors — with Rupert 'cause I really love what he's been doing. I brought up the pitch to him and he said, 'I really love this. I think we should talk about it.' And so it was really just the universe coming together."

"Agent 13" is an adaptation of a 1988 comic book that follows an organization called the Brotherhood, which comprises survivors of the lost civilization of Lemuria. The title character was kidnapped by the Brotherhood as a young boy and trained to be one of their top spies. When Agent 13 realizes the group has been corrupted, though, he sets off to take them down.

Fans are speculating that Theron will play one of the agent's two sidekicks — his seductive lover, China White, or his beautiful, devoted assistant Maggie Darr — but the actress isn't sure which character she'll play. "You know, we're writing it right now so it's a very, very loose pitch," she said, "but it's an alternate world story so it's big and epic and cool."

With the Wyatt project still in its early stages, fans can get their fill of evil Theron as the wicked Queen Ravenna in "Snow White" when it opens on June 1. Her character's cruel nature, she said, gave her license to act like a jerk between takes.

"I'm like yelling for sandwiches and coffee," she joked. "And then, Chris [Hemsworth] comes by and he's like, 'You're not shooting right now, Charlize!' And I say, 'Your head on a silver platter!' And he says, 'No, you're not the queen right now.' And then it crushes me, and I cry, and I deal with it."

While Theron hasn't ruled out playing the nice girl, she teasingly said that for now she takes on the roles most familiar to her. "I stick with what I'm good at," she said, laughing.
