While fans eagerly await the June release of [movie id="420622"]"The Twilight Saga: Eclipse,"[/movie] one of the film's stars, Kirsten Prout, is opening up about joining the cast for the third film in the franchise. She plays Lucy in the film, the vampire who turns Jasper (Jackson Rathbone) into a vampire. And she says she enjoyed getting to embrace her inner bad girl for the film.

"I've always been on the good side. I've never played a villain in my entire career. I'm the girl next door, or the girl who helps out, or the girl that makes an innocent escape. For once, I got to look all innocent and have that angelic quality, and then, all of a sudden, turn into something really dark," Prout, who starred on the TV series "Kyle XY," told Iesb.net. "That was fun for me. That was the first villain that I've ever played."

Like Rathbone's onscreen sister, Rosalie, played by [article id="1626866"]Nikki Reed[/article], Prout gets in on the backstory action in the movie as well. "Without revealing too much, Lucy is one of the vampires that turns Jasper, played by Jackson Rathbone. Jasper gets turned while he is an officer, and I'm one of the vampires that causes Jasper to be turned during his military career," Prout added. "Lucy appears to be an innocent little victim, and then she turns into something a lot more sinister."

Not only did Prout get along "really well" with Rathbone, she also raved about the franchise's third director, [article id="1621601"]David Slade[/article]. "He's a great guy because his way of working is so open. He just says, 'Do what you do,' and lets you play with it. If he has notes, he gives them to you, but he's a very open director. He keeps it light," she explained. "He loves his job and he's very serious about it. He's a great director."

But before she got to work with Slade, she had to audition for her role. And instead of reading from the script, she read straight from the book. Why? Because all things "Twilight" are shrouded in mystery until they are ready to be revealed to the film's stars. "The technique that they used for the audition was that they made the scenes exact transcripts from the book. It was very strange to audition with them because they were written to be read and they weren't adapted yet. They didn't give the screenplay out. So, the audition side was just reading a page of 'Twilight' and reading the lines that were interspersed between the descriptions. That's what it was like," she revealed. "They could never distribute that. Even when I got the job, the secrecy was so high in the 'Twilight' world."
