Chiller Theatre, or Chiller Theater, was a late-night horror and science fiction movie program on WIIC/WPXI, Channel 11, Pittsburgh, Pennsylvania. It aired from September 14, 1963 to January 1, 1984. It was hosted by Bill Cardille, known to fans as "Chilly Billy". It was a Saturday night tradition for two generations of Pittsburghers. Two films were shown, one starting at 11:30 p.m. and the second starting at about 1:00 a.m. In between films, and at random times during the films, breaks were taken for skits such as reports from the "PSS"; in these skits, Bill Cardille would go into another part of the WIIC studios and pretend he was broadcasting from the (nonexistent) Pittsburgh Subway System. Other characters (portrayed by Cardille) included Captain Bad, Maurice the Matchmaker, and Mr. Magnificent. Cardille and WIIC publicist Robert Willis wrote the skits and sometimes Channel 11 staffers were enlisted to play bit parts. At the end of the show, Cardille would sit on a stool and banter with the studio crew.
Chiller Theatre was so popular in Pittsburgh that it kept Saturday Night Live off of its NBC affiliate WIIC in Pittsburgh for four years. Finally giving in to pressure from NBC, Chiller Theatre was forced to follow SNL at 1:00 a.m. where it was reduced to a single feature movie program.
The show was remembered for several unique features, one being its theme song, "Experiment In Terror" performed by Al Caiola, written by Henry Mancini. The original set was meant to be a laboratory. It was changed to a castle motif when a cast of supporting characters was added in later years. That cast included Terminal Stare (Donna Rae), Georgette the Fudgemaker (Bonnie Barney), Norman (Norman Elder), and Stefan the Castle Prankster (Steve Luncinski). During breaks in the movie, Cardille would perform several sketches, like reciting horoscopes, trivia, and telling a series of corny jokes to a giggling skull.
The show featured many guests over the years, including: Rod McKuen; Phyllis Diller as a monster Chilly Billy creates; Barbara Feldon as "Agent 99" from Get Smart; Lorne Greene; Albie And Friends performing their 1974 NIK single "Hexorcist World Premiere"; Vincent Price; Richard H. Campbell of "The Gang"; Jerry Lewis, promoting the Muscular Dystrophy telethon; and Bruno Sammartino.
