Eureka's Erica Cerra takes to the big screen in her next project, Percy Jackson & the Olympians: The Lightning Thief. And she's in some mighty fine company, as co-stars include Uma Thurman, Rosario Dawson, Pierce Brosnan, Sean Bean, Kevin McKidd, Catherine Keener, Melina Kanakaredes, Steve Coogan and Logan Lerman as Percy Jackson.

Directed by Harry Potter veteran Chris Columbus, the film is a fantasy based on the first book in Rick Riordan's popular series. In the story, a young modern-day boy named Percy Jackson learns that he's the half-human/half-god son of Poseidon (McKidd) and embarks on a journey of adventure and self-discovery that also involves warring gods. Cerra plays Hera, the goddess of marriage and wife of Zeus (Bean), the god of lightning.

"I'm a big Harry Potter fan," said Cerra during a recent, exclusive interview. "I have all the books. I've seen all the movies a billion and one times. When I heard what Percy Jackson was about I read it and pushed, pushed, pushed to be in the movie. So I was absolutely thrilled when I got a role, and then I was sitting in a room with Sean Bean and Kevin McKidd and Melina Kanakaredes, who plays Athena. It was a wonderful experience, and I'm a very big fan of Chris Columbus, so that was really cool as well. In the novels, in the other stories, Hera and Zeus show up to help Percy, so hopefully they will also in the [sequel] scripts."

As much as she enjoyed working with Columbus and sharing scenes with Bean, McKidd, Kanakaredes and Lerman, Cerra saved her greatest excitement for a discussion about the film's costumes. "We were wearing these absolutely stunning silk dresses, myself and the rest of the goddesses," Cerra said. "The wardrobe is spectacular. The look of them, it's a similar idea to Roman togas. They're really elegant and lovely. A lot of our jewelry was made the way they made jewelry in the early Greek times. They'd take metal and hammer it out. It was spectacular. And it all cost a fortune. I was like, 'Can I take this [dress] home?' And they weren't having it. They were like, 'No.' I think we all tried."

Percy Jackson & the Olympians: The Lightning Thief opens nationwide on Feb. 12, 2010.
