Harper’s Island – CBS’ newest drama, which premiers tonight in the US, has a couple guest-alums Richard Burgi (Firefly – Lieutenant Womack) and Christopher Gorham (BtVS – James Stanley, also Henry on Ugly Betty).

According to Wikipedia, the television show is a horror/drama, described as Scream meets 10 Little Indians (by mystery writer Agatha Christie). The central plot is a murder mystery. Friends and family attending a wedding celebration on a secluded island off the coast of Seattle begin dying one by one. The island was also the scene of a famous series of murders seven years prior.

In addition to a web series (Harper’s Globe) based on the show, CBS’s multimedia promotion includes a live online chat on a Fancast Forum each Friday with the “murder victim” from the Thursday night U.S. broadcast, where questions and comments from viewers trying to solve the mystery are encouraged, as well as providing a behind-the-scenes view from the series.
