Amanda Seyfried has come a long way from the dimwitted Karen in "Mean Girls," having recently wrapped a four-year run on HBO's "Big Love" and achieving box-office success with "Dear John." But that's not to say that the actress isn't worried about getting stereotyped. She doesn't want to become synonymous with the horror genre after "Jennifer's Body," for instance, or even as a romantic lead due to her work on "Dear John."

In order to combat typecasting, Seyfried took the radical route of becoming a call girl and seducing Liam Neeson and Julianne Moore. Not in reality, of course, but as the title character in "Chloe," a seductive thriller that Seyfried intentionally pursued to avoid getting pinned to any one genre.

"I'm so many levels beyond [what I'm used to] because ['Chloe' is] so intense, and it really is a character that's just kind of sick, and that's really fun to play," Seyfried told MTV News. "It makes me feel like I've evolved a little bit as an actor too. I mean, maybe I haven't, but it makes me feel like I have!"

Seyfried said she's learned a lot about her craft from co-stars like Meryl Streep in "Mamma Mia!" and Moore in "Chloe." "When you watch somebody like Julianne and Meryl and you can be around them for 12 hours a day, you absorb it all, kind of what they're doing, how they behave, how they respond to things. It's something that becomes innately part of how I behave as well," Seyfried said. "[Moore is] very professional and she separates her work from her real life, her family, and she's completely focused at all times, but she can also have fun between takes."

Beyond acting, Seyfried learned something else from Moore: "She's a great kisser! She's beautiful. She's a great actress. What more can I say? It was amazing."
