Continuity mistake: The drawing of Waxflatter and his friends that Watson shows Holmes is totally different from the one Holmes shows Elizabeth in the room Rathe assigned to her. Also, it can be observed in the same scene that the hands on the drawing (supposedly of Holmes and Watson) are those of an adult (or even an old man). (01:10:46)
Revealing mistake: There are several instances where you can see that the bandages used to wrap up the girls are pre-assembled. When the first girl is "waxed" you can see there are no joins between the bandages, they are all in one piece - almost like a body stocking. You can also see this later with Elizabeth, and it becomes more significant because you see the bandages being wrapped around her head as normal, and then when Watson pulls them off, they come away in one piece like a balaclava, which of course shouldn't happen.
Revealing mistake: When Mrs. Dribb is wrapping Elizabeth up in bandages, you can just see the outline of the bald cap she is wearing. There is a straight line just above her eyes that goes nearly right across her forehead.
Continuity mistake: Towards the end when Rathe is about to fight Sherlock, among several things a sword magically appears at Holmes' feet.
Suggested correction: This is incorrect. Holmes carries a sword from the moment he and Watson leave the pyramid. He drops it to the ground when Elizabeth is shot and picks it up again to fight Rathe.
Revealing mistake: Actress Susan Fleetwood's (Mrs. Dribb) hair is lumped together under her skull cap, creating an obvious and pronounced bulge in the back of her head where the base of her ponytail is.
Continuity mistake: After Professor Rathe dismisses Elizabeth, Watson, and Holmes from his office, Holmes turns towards Rathe whose arms are hanging down, but the next closeup shot of Rathe shows his arms crossed across his chest.
Other mistake: The size-proportion of the pyramid seems too small in order to allow the whole structure beneath it, the whole temple and all the people inside.
