In the mid-'70s, Omega Man and Planet of the Apes were hot sci-fi films garnering a lot of public interest, so when you're looking for a new comic book title, why not merge themes from both hit movies and give it a vampire twist? Surely it can't lose, right? Sadly, 1975's Planet of Vampires didn't cut it and only made it for three issues before the title was canceled by its publisher.
