It surely didn’t help the OK but not great Island of Burning Doomed that over here it was the bottom half (!) of a bill with the goofy kiddie flick Godzilla’s Revenge. I can’t imagine many people who liked one got much out of the other.
I’m more intrigued by this French poster, which runs away from what the film is about altogether. Were they trying to suggest it was a Dracula flick?
