Kolchak: The Night Stalker is een Amerikaanse serie van de zender ABC. De serie ging in première in 1974.
Kolchak was originally two made-for-TV movies that aired in the early 70's, and featured the adventures of Carl Kolchak, a down-on-the heels reporter who ran afoul of a vampire in Las Vegas and an alchemist in Seattle. These movies proved popular enough that they were spun off into a series, which placed Kolchak in Chicago with the Independent News Service. Each week for 20 weeks he investigated various supernatural and supranatural creatures, ranging from aliens to vampires to Aztec sacrificial cults. Although it only lasted one season on ABC, Kolchak has remained a cult favorite and been kept alive through the efforts of creator Jeffrey Grant Rice, Mark Dawidziak, and the folks at Moonstone Comics, who have two Kolchak comics going (see Links). There's an anthology of Kolchak stories coming out this year and discussion of a new Night Stalker (2005) series produced by The X-Files's Frank Spotnitz for ABC.
Various Chicago citizenry are being killed with medieval weaponry. Upon investigating, Kolchak finds that they were all tied to the conversion of a small museum into a disco. It turns out that the museum houses the armor of Guy de Metancourt, a misanthrope who swore upon his death that his final resting place would never know gaiety and laughter. Now, his ghostly armor animates and kills those who would disrupt his resting place. The only way for Kolchak to stop the unchivalrous knight is to destroy it with a holy axe blessed by the pope.
