# Harper's Island

Harper's Island is an American horror mystery limited series created by Ari Schlossberg for CBS. Schlossberg, Jeffrey Jackson Bell and Jon Turteltaub served as executive producers. The series features an ensemble cast led by Elaine Cassidy alongside Christopher Gorham, Katie Cassidy, Cameron Richardson, Adam Campbell, C.J. Thomason, and Jim Beaver. The plot follows a group of family and friends that travel to the titular locale for a destination wedding, only to learn that there is a killer among them. At the center of the mystery is Abby Mills (Elaine Cassidy), whose mother was one of several people murdered by John Wakefield seven years prior.
The series premiered on April 9, 2009, and was marketed as a thirteen-week limited event. The final two episodes aired on July 11. By the end of its run, Harper's Island averaged 9.36 million viewers, ranking #50 in Nielsen ratings. The first three episodes aired on Thursdays, but was moved to Saturdays during the week of April 28. Because of this, Global Television Network premiered the following episodes two days prior to the United States.
The series was initially intended to be an anthology series featuring a new setting and characters in the second season. However, on July 14, 2009, CBS cancelled the series after one season. The show gained a strong cult following since its release, with some critics and fans noting it as being ahead of its time.

## Plot

The show takes place on Harper's Island, where John Wakefield went on a killing spree and murdered a number of people before supposedly being killed by the island sheriff, Charlie Mills. One of the victims was the sheriff's wife. After her death, Sheriff Mills sends their daughter, Abby, to live with family in L.A. and she hasn't returned since. After 7 years, Abby is finally returning to the island for her best friend Henry's wedding, but now the killing starts again and everyone is a suspect.

## Development

In March 2008, CBS ordered a 15-minute pilot presentation of the project. In May 2008, the show was retooled, with Jeffrey Bell coming on board as showrunner and Jon Turteltaub as an executive producer. Schlossberg remained on board as a co-executive producer along with Karim Zriek and Dan Shotz.
Bell subsequently rewrote the first episode, which Jon Turteltaub would direct. During the retooling process, six of the pilot presentation's fifteen original cast members were replaced, including Ryan Merriman (Henry Dunn), Samantha Noble (Trish Wellington), Bill Dow (Sheriff Mills) and Bill Pullman (Uncle Marty). The roles of Thomas Wellington and Hunter Jennings were also recast.
Actors who remained with the show from pilot-presentation to the aired television pilot include Elaine Cassidy, Cameron Richardson, Adam Campbell, C.J. Thomason, Matt Barr, Cassandra Sawtell, Brandon Jay McLaren, Chris Gauthier and Sean Rogerson. The series was shot on Bowen Island, an island municipality about two kilometers west of Vancouver, British Columbia, and at the University of British Columbia.
The actors and actresses were not told about their characters' deaths until the day that each script was given. The only two actors to know the length of their contracts were Richard Burgi, as his death was seen as a major turning point in the series, and Harry Hamlin, as his contract was for a single episode.
