Cooper's dream is mostly made up of deleted scenes from Northwest Passage (1989) in its alternate international edit.
This episode was watched by an audience of 19.2 million households in the United States, equating to roughly 21 percent of the available audience.
The episode's ending was parodied in "Who Shot Mr. Burns?", a 1995 two-part episode of The Simpsons (1989), in which Dale Cooper and The Man from Another Place were replaced by the characters of Chief Wiggum and Lisa Simpson, respectively. The backwards speech and unexplained shadow moving across a wall were included in the parody, which takes place in a detailed recreation of the Black Lodge.
Frank Byers, the episode's director of photography, has stated that the chief inspiration for his choice to use wide-angle lenses and soft lighting throughout the episode was the Orson Welles film Touch of Evil (1958).
The episode marks the first time that "Invitation to Love" which was a soap opera that aired in Twin Peaks, Washington as of early 1989, is featured. The series followed the travails of the inhabitants of "the Towers," a lavish high-rise apartment complex, and somehow paralleled the events of Twin Peaks.
