One of my favorite childhood SCI FI Film's later became a CULT CLASSIC - 1965 Planet of the Vampires - AKA: Demon Planet AKA: Terrore nello Spazio, lit. 'Terror in space') - was based on an Italian Science Fiction Short Story written by Renato Pestriniero in 1963 and published in Interplanet 3 Magazine. Finally - a deep dive into the internet and a translation from Italian to ENGLISH - thanks to GOOGLE. The original short story has surfaced after 57yrs. SEE ATTACHED:
