Kolchak: The Night Stalker is an American television series that aired on ABC during the 1974–1975 season. The series followed wire service reporter Carl Kolchak (Darren McGavin) who investigates mysterious crimes with unlikely causes, particularly those involving the supernatural or science fiction, including fantastic creatures. The series was preceded by the two television movies, The Night Stalker (1972) and The Night Strangler (1973). Although the series lasted only a single season, it rapidly achieved cult status and has remained very popular in syndication.
Chris Carter cited Kolchak as a "tremendous influence" in creating his franchise The X-Files. In 2005, inspired by that success, The X-Files producer Frank Spotnitz resurrected the series as Night Stalker, with a new cast and characters, as well as subsequent novels and comic books. The new series was a ratings bomb, however, and was quietly cancelled after only six of the ten episodes which had been produced were aired.
