Voodoo Heartbeat (aka The Sex Serum of Dr. Blake) is a 1973 exploitation Horror film from writer/director Charles Nizet.


Voodoo Heartbeat is about an experimental youth serum that transforms a rogue scientist into a fanged beast out for blood.

The movie was shot in ATF Studios in Las Vegas, Nevada.[1]

Back in 1972, the president of the (now defunct) TWI International, Robert Saxton, announced that Mike Zapata, one of the actors in the movie, was going to be the top star of the motion picture and television mediums in a couple of years, but as of 2023, this was his only film role. He also mentioned making the sequel, Dr. Blake's Revenge, with Ray Molina Productions,[2] but this had fallen through over time.


For a long time, the movie was not available to purchase through VHS or DVD. In 2013, a forum member going by the name Paul Haight embedded two minutes of footage from Voodoo Heartbeat that has since been deleted from YouTube.[3] Only a few still images, newspaper ads, and promotional posters can be seen.

On September 22nd, 2023, Vinegar Syndrome announced a Blu-ray box set called "Vinegar Syndrome's Lost Picture Show" that included 10 thought-to-be-lost films remastered on Blu-ray on which Voodoo Heartbeat was included in the catalog of films listed in this set, making the film commercially available in November. On November 24th, 2023, the film was officially released via Vinegar Syndrome's Blu-ray set.
