** Joining Johnson is Conrad Brooks, another Creator/EdWood regular and "the John Gielgud of bad movies", according to ''The New York Times''.
* RealLifeRelative: The wife and sons of Coleman Francis play the distraught wife and wandering kids in the movie.
* ThrowItIn: 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.
