A reporter from The Garden Island newspaper went undercover posing as one of the prospectives. But he could not give away too much as he was asked to sign a non-disclosure agreement by the production company. The reporter said that some of the people in the long queue also bought accessories.

According to the description in the press release for the auditions, which were conducted by executives from EBB Tide Productions Casting, they were looking for men, women, and children who are comfortable in water.

Apparently no lines were to be read and only a brief interview was involved.

"There's too many people they just going to go through everybody and pick out the best," he added.

Filming in Hawaii is scheduled to begin in April, according to one of the producers, Patrick Crowley. In an interview with the Honolulu Pulse, he revealed that filming will go on for about six weeks in Hawaii, and scenes will be shot in Oahu and Kauai.

The film will hit theaters on June 12, 2015.
