Musician Webb Wilder has a small role as a private detective in this film. He also played a private detective in the short films, "Webb Wilder, Private Eye in The Saucer's Reign" and "Horror Hayride", which partially inspired "The Purloined Guitar".
The title, "The Purloined Guitar", is a reference to "The Purloined Letter" by Edgar Allan Poe. Poe is often credited as having invented the detective story, and "The Purloined Letter" is one of his earliest works in that genre.
