Continuity mistake: When Paula escapes from her house and runs through the cemetery she doesn't have shoes, but she's wearing a pair of slippers when the man finds her unconscious besides the road. (00:34:00)
Continuity mistake: When the flying saucer is seen taking off from the cemetery, it is saucer shaped. However, when it is on the ground the ship appears to be in the shape of a square building. (00:37:05)
Continuity mistake: As they look into Tor Johnson's empty tomb, one of the police officers says it looks like (the dirt) has fallen into the grave. In the next shot as he goes into the hole there is no dirt in it. (00:40:00)
Continuity mistake: As he interviews Col. Edwards, the phone wires hanging off the side of General Roberts' desk move between shots without anyone touching a phone. (00:41:00)
Continuity mistake: In scenes at the general's office, a large wall map of the U.S. is in the background. In some of the closeups you can see that it's a Santa Fe railroad map - and in others the words "Santa Fe" on the logo are taped over. (00:42:05 - 00:45:30)
Continuity mistake: As he interviews Col. Edwards, General Roberts' clock moves 20 minutes throughout the scene yet only 2 minuets of movie time elapse. (00:43:55)
Continuity mistake: The Ghoul Man is turned to bones by a ray from the alien spaceship and Col. Edwards throws the cape off of the body revealing the horrible sight. A couple of shots later they wake up Patrolman Kelton who is now lying on the cape. (00:55:30)
Continuity mistake: At the grave yard it's pitch black out but you can see the reflection of a studio light in the police car windshield. (00:57:15)
Continuity mistake: As Eros talks about the solaminite, the blinking light on the table in the alien spacecraft stops blinking between shots without anyone going near it. (01:07:10)

Continuity mistake: At the beginning of the scene where the pilot's wife, Paula, is almost attacked in her bedroom by (not) Bela Lugosi, look at the three pictures on the wall above the bed. One of the pictures changes, then changes back (occurs only in the colorized version).
Continuity mistake: In the scene on the back yard portico where the cop is backed up to the other cast members, the male vampire knocks him down to the ground. It then shows the green 'rays' shooting off the landed saucer and the vampire crumples to the ground. A cast member throws off the vampire's cape revealing a skeleton. At this point the cop is missing from where he fell in front of the vampire. Next shot someone helps the cop up from the ground where he is lying almost touching the revealed skeleton. Also, the skeleton used for the skinny male vampire is the same one used for the grossly overweight Tor Johnson.
