Several elements of this film inspired scenes in David Lynch projects. To begin with, there is the Twin Peaks sign at the beginning of the film which served as obvious inspiration for the title card and setting of Lynch's television series of the same name. Also, a scene or two later (the infamous "opening" scene,) when Kelly is in here garage, the killer mentions that he has "killed twice before" - this is something which "Bob," the supposed killer from "Twin Peaks" also mentions. This scene also has uncanny resemblances to a scene in Lynch's Wild at Heart where Willem Dafoe's character, Bobby Peru, has Lula Fortune in his filthy grasp and is talking to her similarly. Later in the film, we find out that the killer in "Experiment in Terror" is actually called Garland "Red" Lynch. The resemblance to David Lynch's name is something which the director no doubt noticed, as he also named a character in "Twin Peaks" after him (Major Garland Briggs).

In the scene in which Agent Ripley is informed that Toby Sherwood was found alive and well, the stadium organist is playing the Theme From Mr. Lucky, written by Henry Mancini for the TV series which co-starred Ross Martin.
