For a Herschell Gordon Lewis film, "A Taste of Blood" was very well-made enough to impress Roger Corman, who offered the director a directing gig at working for his production company in Hollywood, which Lewis politely turned down.
The soundtrack regularly uses music from the 1966 Doctor Who story "The Tenth Planet" throughout the film.
During the filming, the co-star Elizabeth Lee began romantically dating Andy Romanoff, who was one of the camera operators. News of the affair apparently displeased Herschell Gordon Lewis who felt that Lee was distracting Romanoff from his work on the film. After filming ended, Lee returned to her home in Chicago while Romanoff stayed in Miami, but after that refused to work for Lewis anymore and he eventually got married to Lee.
