"The Twisted Image" is the first episode of the show "Thriller" (aka. "Brois Karloff's Thriller"), which ran from 1960 to 1962 and was hosted by Horror deity Boris Karloff. Karloff introduces every episode (his introduction of the episode includes an introduction of the actors, which seems very vintage and a little odd from today's point of view), but (unlike it was the case in the preceding show, "The Veil") he sadly doesn't appear as an actor in the actual episodes.
This very decent start to the series features a young Leslie Nielsen in the lead. Nielsen plays Alan Patterson, a happily married and successful businessman, who finds himself stalked both by the obsessively lovesick young beauty Lily Hanson (Natalie Trundy) and the jealous and mischievous crook Merle Jenkins (George Grizzard)...
Nielsen is likable as always, Natalie Trundy is very cute and therefore not easy to see as a threat. George Gizzard is very good and effective in playing a psychopath. Even though it will not scare anybody's pants off, the episode is suspenseful and exiting enough throughout its 49 minutes. Overall this is a very decent start to the series, and the best of the first five episodes which I've seen. The early episodes generally tell tales of mystery and crime, whereas the show became focused on Gothic Horror tales in the later episodes (which therefore should be more interesting to myself and most of my fellow Horror fans). "The Twisted Image" is entertaining, but by no means a must-see.
