These days, a lot of people forget that Patrick Dempsey was in Scream 3. Dempsey had a major role as Mark Kincaid, a detective tasked with investigating the newest Ghostface murders during the events of Scream 3. He was considered to be one of the killers at one point during the writing, but ultimately winds up as a survivor that pursues a romance with Sidney at the end of the film.
