“Hawaii Five-0” will hold an open casting call Aug. 28 for adults of all ages and ethnicities to be considered for speaking roles and as background extras.

The “Five-0” producers are aiming for authenticity when it comes to portraying Hawaii, said Rachel Sutton, the casting agent for the show. From hot surfers to aunties in oversized muumuu to sunburned tourists — everyone is welcome, she said.

“We definitely want to present Hawaii in the most realistic way and the reality of Hawaii is all of these different looks of people,” she said. “We need to fill the whole palette.”

No experience is necessary. The casting call will be from 10 a.m. to 4 p.m. Aug. 28 at Aloha Tower Marketplace. If possible, bring a “headshot” photograph and a resume but plan to be photographed.

“Hawaii Five-0” premieres with a sneak preview Sept. 13 at Sunset on the Beach at Waikiki. The network premiere will be Sept. 20.
