Trivia: The Beast of Yucca Flats
- Author Appeal: The "Breast of Yucca Flats" scene, included because Coleman Francis wanted a nude scene.
- Fan Nickname: "The Breast of Yucca Flats" for the random topless scene at the beginning.
- Hey, It's That Guy!: Tor Johnson! Furthermore Tony Cardoza is not only one of the KGB men, but the helpful neighbor guy at the end, and the guy run off the road is Joe from The Skydivers.
- Joining Johnson is Conrad Brooks, another Ed Wood regular and "the John Gielgud of bad movies", according to The New York Times.
- Real-Life Relative: The wife and sons of Coleman Francis play the distraught wife and wandering kids in the movie.
- Throw It In: The Beast was supposed to simply die at the end of the film. However, a wild rabbit walked onto set and Tor Johnson got up and kissed the rabbit, then dropped back down. Francis liked the scene so much he made into the final shot of the movie. Possibly the one choice he ever made that improved one of his films.
- Type Casting: Tor Johnson as The Beast.
