Last season on Hawaii Five-0, fans had the chance to vote on the ending of an episode by submitting who they thought was the installment’s culprit after all the evidence was given. This season viewer participation reaches an entirely new level of interactivity; the show is allowing fans to shape an entire episode. Through October 31, fans can vote on key story elements like Scene of the Crime, The Victim, The Murder Weapon, The Evidence, The Suspect, and The Takedown; each category contains seven options to choose from. For example, the murder weapon can be flame thrower, a spear gun, or even a poisonous toad; a five inch stiletto, however, is currently the frontrunner. And this is only Phase 1. In January fans can vote on props and wardrobe, in February music, and in March the episode title will be chosen. Production on the episode begins in February 2014 in Oahu, Hawaii and it will air sometime later this season.

“Viewers loved helping figure out the ‘whodunit’ episode last season,” said exec prod Peter Lenkov. “Now, we want to up the ante by having viewers’ input on the production of a show. From story to props, viewers will help call the shots. And yes, this is fun for me when I get to see just how creative our writers can be when the key elements are chosen.”

“We are always looking for ways to engage with our viewers and reward fan loyalty,” added Glenn Geller, exec VP at CBS. “A Fan-Built Five-0 is another great example of how Peter Lenkov thinks outside the box in order to deliver exciting and original stories to the viewers.”
