Above-average made-for-TV movie...
Made for ABC television in 1972, “The Night Stalker” was written by Richard Matheson based “The Kolchak Papers” by Jeff Rice. Filmed in California in 12 days on a budget of $450,000, it stars Darren McGavin (“A Christmas Story”) as Carl Kolchak, a loud, arrogant newspaper reporter frequently locking horns with editor Vincenzo (Simon Oakland). Kolchak is assigned to investigate a series of murders in Las Vegas in which the victims, all young showgirls, are drained of their blood.<br /><br />Kolchak probes, puts together clues, and follows leads, but the police try to keep him away from the case. When he suggests the murderer is a vampire, the mayor, police chief and his editor think he’s crazy. They think the killer is a psychopathic serial killer and regard his theory as sensationalistic nonsense. The editor never prints his story fearing it will needlessly alarm the public, but Kolchak, now obsessed with solving the mystery, sets out alone one night to the home of Janos Skorzeny (Barry Atwater), a man he suspects of being the murderer.<br /><br />McGavin turns in an energetic performance as Kolchak, his intensity giving the movie a driving force and adding moments of humor. His performance as headstrong, grouchy Kolchak is the heart of the movie and the main reason the film works so well. Because Kolchak hopes getting a huge story will propel him back into the big time in New York City, there’s a lot at stake.<br /><br />The supporting cast includes Carol Lynley, Claude Akins, Kent Smith, Ralph Meeker, Elisha Cook, Jr., Charles McGraw, and Larry Linville.<br /><br />Writer Matheson incorporates lots of vampiric lore into the movie: a vampire must rest by day, needs human blood to survive, fears the crucifix, possesses enormous strength, and is impervious to bullets. Because this is a TV movie, there isn’t the usual excessive blood and gore associated with vampire flicks. “The Night Stalker” was so successful that it led to a second made-for-TV movie, “The Night Strangler,” in 1973 and a TV series in 1974.<br /><br />Bonus materials include audio commentary by film historian Tim Lucas; new interview with director John Llewellyn Moxey; new interview with composer Bob Robert; interview with director Dan Curtis; special edition booklet; a “Burnt Offerings” trailer; and newly commissioned cover art.

Here is a brief synopsis of the title : BRAND NEW HD RESTORATION IN 4K! An investigative journalist takes a stab at the supernatural. This unforgettable first entry in the Night Stalker series introduced the world to the quirky reporter with a penchant for the paranormal and became one of the top-rated TV movies of all time. Investigating a series of Las Vegas murders, Carl Kolchak (Darren McGavin, The Night Strangler) discovers that each victim has been bitten in the neck and drained of blood. Though Kolchak's outlandish theory about the murders gets him nowhere with the police, his initiative to apprehend the killer himself gets him into hot water... with a modern-day vampire. The great John Llewellyn Moxey (Nightmare in Badham County) directed this Dan Curtis (Burnt Offerings) production featuring Carol Lynley (The Poseidon Adventure), Simon Oakland (The Hunting Party), Ralph Meeker (Big House, U.S.A.), Claude Akins (A Man Called Sledge), Charles McGraw (The Narrow Margin), Kent Smith (The Spiral Staircase), Elisha Cook Jr. (I Wake Up Screaming) and Larry Linville (TV’s M*A*S*H). Teleplay by legendary sci-fi/horror writer Richard Matheson (The Incredible Shrinking Man)..
