Katie Cassidy, late of the CW's Supernatural, is heading for a wedding... playing the bride-to-be on Harper's Island.

The CBS midseason drama revolves around a collection of family and friends who RSVP for a destination wedding but instead find themselves subject to a Ten Little Indians-style nightmare.

Playing the on-screen fiancée of Christopher Gorham ( Ugly Betty), Cassidy replaces Samantha Noble, who filled the role in the series' original presentation. - Matt Mitovich
