CHICAGO (CBS) — If you plan to audition for the new Star Wars movie on Thursday in Chicago, you should probably leave your stormtrooper armor or Jedi robe and lightsaber at home.

Auditions at Park West Theatre in Lincoln Park are expected to bring out legions of Star Wars fans for only two roles.

Carole Dibo, founder of the Actors Training Center, suggested aspiring actors not dress up like their favorite Star Wars character.

“That’s not going to help,” she said. “It might actually make you look a little silly.”

Dibo said it’s not about your costume when you audition for a big-budget movie, it’s about how your performance.

“It’s not a Halloween call, it’s a call for a movie,” she said.

She said those who usually get parts at auditions like this usually have a certain presence.

“They walk in with confidence. They look the people behind the people in the eye. They say hello. They are grounded,” she said.

Casting directors at the Star Wars Episode VII audition are looking for one actor and one actress.

The female role is for a character named Rachel, described as a beautiful, smart, athletic, street-smart and strong 17- to 18-year-old hoping to move away from a dangerous childhood to a better life.

The male role is for a character named Thomas, a handsome, smart, athletic, capable, and courageous 19- to 20-year-old who grew up without a father figure.

Auditions will be held from 3 p.m. to 8 p.m. at Park West Theatre, at 322 W. Armitage Av.
