Incidentally I have the DVD collection of the short-lived horror show of the 1970's Kolchak: the NightStalker, which the X-Files creator Chris Carter cites as a major source of his own inspiration.
Yep,
The Night Stalker was a great, but sadly short-lived series. Some of the episodes (like the one with the headless motorcyclist) were genuinely creepy, but stars Darren McGavin and Simon Oakland kept things light in their verbal sparring scenes together. One of the reasons why the show didn't survive was because many felt the episodes were too similar. A strange occurrance happens. Kolchack believes it's the work of the supernatural. His editor and no one else will believe him. Kolchack eventually solves the case and proves to have been right. I suppose critics were looking for more depth. But it is an excellent show, far superior to the short-lived remake from a couple years ago with Stuart Townshend as a much younger Kolchak. That version gave the character more of a backstory, but it didn't stay on the air too long.
If you haven't, check out the two made-for-TV features that were the inspiration for the series.
The Night Stalker (1971) introduces Kolchack, a maverick reporter investigating a string of unsolved murders in Las Vegas in which the bodies are drained of blood. Kolchack rightly assumes the killer is a vampire, but of course, no one believes him. At the time, this was the highest-rated TV movie ever.
The Night Strangler (1973) has Kolchack now working in Seattle (he was fired from his Vegas beat at the end of the first film), where he becomes involved in another series of murders, in which the perpetrator this time is a mysterious doctor who has discovered immortality, but he must kill to acheive it. He resurfaces every ten years or so for fresh victims. I'm sure this film inspired Chris Carter's Eugene Tooms in
The X-Files.
Both films are included on the same DVD.
