My review was written in July 1985 after watching the film on CBS/Fox video cassette.
"The Killing Hour" is a well-crafted but mediocre thriller. Lensed in Manhattan in 1981, low-budget indie was picked up by Jensen Farley Pictures and retitled (more appropriately to subject matter) "The Clairvoyant", subsequently acquired by 20th Century Fox after JFP went under, but unreleased theatrically, appearing instead as a cassette via CBS Fox.
Perry King toplines as Paul McCormack, Mack for short, a tv newsman/phone-in talkshow host who successfully exploits on the air a series of handcuffed-victim murders to increase his ratings and secure job advancement. At first he is aided with inside info by policeman Larry Weeks (Norman Parker), who improbably moonlights as an unfunny standup comic/impressionist (he has to identify his carbons, such as Al Pacino or Geroge Burns for the viewer), but his sensationalist reporting soon puts him at odds with the police led by Lt. Cullum (Kenneth McMillan).
Both the police and Mack are aided by Virna Nightbourne (Elizabeth Kemp), a young artist who is clairvoyant and makes drawings of each murder unconsciously.
After a promising beginning, spotlighting the ingenious rather than gory murders, pic becomes sluggish. Because of the script's paucity of suspects, the identity of the killer is quite predictable. Acting is okay and direction by Armand Mastroianni (previously known for "He Knows You're Alone") is effective within the screenplay's limitations. Lensing by British cameraman Larry Pizer is excellent.
