Rosario Dawson, the butt-kicking babe from "Sin City" and a star of "Clerks II," has gone geeky.

On Thursday, the 27-year-old actress appeared at Comic-Con, the country's largest comic book convention, to discuss her foray into the genre.

Dawson is the co-creator of "The Occult Crimes Taskforce," a new comic book series that tells the story of the supernatural gone wild in New York City.

Dawson was the inspiration for Sophia Ortiz, a detective who "deals with crimes of the magical context," she said.

Writer David Atchison described the series as "'CSI' meets Harry Potter."

During a question-and-answer session with fans, Dawson said in many ways working on a comic book is more fulfilling than film.

"This really is the most exciting thing I've been doing," she told the crowd. "As an actor, you're only a third of the production. With this I get to be so much a part of all of it."

Working with Atchison and artist Tony Shasteen, Dawson contributes story lines and character development to the four-book series that she hopes to see adapted into a film and video game.

Unlike Hollywood, the comic-book world doesn't deal in false flattery, she said.

Comic reviewers offer "very intelligent criticism, which is really sorely lacking in film reviews right now," Dawson said.

Her other upcoming projects include Quentin Tarantino's "Death Proof" and "Sin City 2," which begins shooting next year.
