Continuity mistake: In the final scene on the bridge, Spock and McCoy are wearing coloured arm bands which identify their departments: Spock's is orange (for Science) and McCoy's is green (for Medical). In the very last shot, Spock is wearing the green band and McCoy is wearing the orange one (corrected in the 2022 re-release of the Director's Edition).
Continuity mistake: In the beginning, when Mike and Jody raise the hood on the car, Jody's hand holding on to the hood alternates between his right and left hand over three shots. (00:13:10)
Continuity mistake: When the stairs are first shown, there's carpet up the middle of the stairs. At the end when they flee the house it's gone.
Continuity mistake: Lupin's car windows are blown away in the car chase, and he and Gingen break all the remaining shards of glass from them. They then return again when lupin pulls up to the princess' car, then disappear in the following shot.
Visible crew/equipment: Young vampire Danny floats away from the window after being confronted with a crucifix. The effect is quickly ruined when the boom he is sitting on can be seen moving him for 8 seconds. (01:43:40)
Factual error: When Brian fires a rifle at the shark from the boat, he fires the rifle multiple times very quickly. The rifle he is using is a bolt action rifle, which must have a bolt part moved before each fire. He does not touch the bolt.
Continuity mistake: When Watson is conned by the prostitute who says she knows Mary Kelly, she lures him into a closed alley. After Watson has called the police and subdued the attacker, 2 constables arrive and arrest Watson, but as they all leave, a third constable comes from behind the camera. Either he magically appeared, or he walked through the wall behind.
Continuity mistake: When Amanda rushes to get onto the bus to the train station, the door being opened is at the front LEFT of the bus (as viewed from the back). On arrival at the station (5 scenes later), the door opens at the front RIGHT of the bus (as viewed from the back), and in the second camera shot, the driver of the bus can be clearly seen sitting where the door Amanda used to board the bus would be, with no door there.
Continuity mistake: Kindaichi follows the gang of rollerskating thieves in their hideout. The female leader says she has a question about his book, and hands him what he identifies as his book of short stories. He's holding it with the left hand in close-up, but in the next shot it's the right hand. (00:17:40)
Factual error: Harry goes to the synagogue, to go through a register his grandfather's records. But he is holding the Talmud and not a register, which is entirely and Hebrew, and he's looking at it upside down. (01:05:00 - 01:06:00)
Continuity mistake: The babysitter answers one of the early calls saying "Robert, I don't think this is very funny." The pencil and papers have completely changed position on the table. (00:07:30)
