Trivia: Though Phil Silvers is shown prominently in the credits, he has only about 2-3 seconds of screen time at the end of the movie. Silvers suffered a stroke in the early 70's; "The Cheap Detective" was made in 1978. His speech had become slurred and likely affected his performance abilities.
Trivia: The winter scene was shot at Eagle River, Wisc. which is in the deep woods. When the Hollywood crew showed up, they brought along fake trees. Those trees were definitely not needed.
Trivia: In the opening title sequence we see a garbage truck going through the Golden Gate Bridge toll booth. We would find out later that these trucks were used to transport the pods. The truck is traveling southbound from Marin County into San Francisco which is appropriate, (intentional or not) since the book Body Snatcher was set in Mill Valley, in Marin County, about 10 miles from the bridge.
Trivia: During the course of the story, the Vette goes from being red, then painted gold, and finally back to red again. The producers actually had two cars, one red and the other gold, custom made before production began. This was to help speed up the filming. During the course of filming, both cars were stolen, and two more, another red one and another gold one were hastily made to finish production. The original two were shortly recovered, and all four were used as displays at various movie theaters across the country when the film premiered.
Trivia: The Chetniks were not one coherent group, as portrayed in the movie. There were in fact two opposing fractions: the first fought alongside the partisans, the others - founded by Kosta Pecanac (the featured group) cooperated with the Germans. Despite their public enmity, though, they still maintained good relations with each other, one of the facts which led to great confusion about the Chetniks among the Allies - probably the reason why they are portrayed here solely as 'bad guys'.
