Thriller (1960)

Thriller (also known as Boris Karloff's Thriller and Boris Karloff Presents) is an American anthology television series that aired during the 1960–61 and 1961–62 seasons on NBC. The show featured host Boris Karloff introducing a mix of macabre horror tales and suspense thrillers

Plot
Thriller was created by Hubbell Robinson for MCA's Revue Studios. Though remembered primarily as a series that emphasized gothic horror, under producer Fletcher Markle Thriller was initially a series oriented towards suspense and crime drama, in the manner of Alfred Hitchcock Presents. Markle was let go after having completed eight episodes, and replaced by Maxwell Shane. Shane continued in the crime drama mold, though he began to add trappings of gothic horror to a few stories, but he too was replaced after having completed a further nine episodes. The rest of the first season and all of the second was produced by William Frye, who firmly moved Thriller into the format for which it would be most well-remembered, although non-horror crime and mystery stories would still be featured from time to time throughout the show's run.
