????

Deliberate mistake: After Tor Johnson attacks Paula and the police officer, a second officer shows up at the cemetery with half of the license plate on the patrol car taped over so it can't be read. (01:09:55)

????

Trivia: At the beginning Criswell reads, "Can your heart stand the shocking facts about 'Grave Robbers from Outer Space'?" This was the original title of the movie that was changed because of objections by the financial backers.

Deliberate mistake: Whenever we see Vampira, they use the same footage, as she's always in the same place next to or near the wooden mausoleum. (01:10:15)

Revealing mistake: As Tor Johnson holds Paula, the police officer comes up from behind and clobbers him on the head with a wooden stick. He falls to the ground and the entire set including all the trees, shake like they were just in a magnitude 7 earthquake. (01:13:20)

????

Audio problem: Inside the alien spacecraft Jeff Trent shoots at the alien device and they overdub the sound of a bullet ricocheting off of a rock like in an old 50's western. (01:03:55)

????

Continuity mistake: As she is chased by the ghoul in the cemetery, Paula knocks over one of the wooden tombstones and you can see the stand underneath that holds it up. The next time we see it two shots later it's been set straight again. (00:32:55)
