- Look for a young Clint Eastwood as the (uncredited) leader of the jet squadron that attacks the tarantula in the film's climax.
- The tarantula was an actual live spider. Air jets were used to make it move in the desired way over a miniature landscape.
- Referenced in the song "Science Fiction Double Feature" in The Rocky Horror Picture Show. "Leo G. Carroll was over a barrel/When Tarantula ran for the hills."
