Other mistake: When Prot visits the doctor's house, he thanks the wife and the camera is zoomed into his sunglasses. The reflection of his glasses shows the doctor looking at him, but the doctor is standing behind him. (00:53:40)
Other mistake: In the shot where Ramathorne is at the gun range, about to shoot Mac in the bullet proof cup, he is talking to Foster and Rabbit about how they are going to get in to the Spurbury Police Lockup. If you watch him draw his gun, he moves his other hand down to chamber a bullet, the sound effect is heard, but he never actually pulls the action back on the gun.
Other mistake: When Scooby and Shaggy are in the cafe, Shaggy says "Can you believe the cafe ran out of food but we're still hungry." But we can see food behind the counter.
Other mistake: When we see the body of Liz Stride after her throat has been cut, the blood is bright pink. This may be due to the light shining on it, but it's still pink. (Surely by then, the blood would have turned brown after mixing with the oxygen?).
Other mistake: When Romulus talks to Matthew about Leppenraub he says that he knows "the man he works for". The German subtitles translate into "the man who works for him". (00:16:50)
Other mistake: When Joe falls on the bungie, we see him hit his head in an entirely vertical position with his head at the top. This could not have been achieved considering the position he was in in the shot before.
Other mistake: The last shots of Trafalgar square you can see twice a UPS van driving in the background.
Other mistake: When Ann makes fun of the mute at the dinner table, the mute wears a plum-burgundy dress. Later on when Grace runs down to the gate and hears Ann crying, she's wearing the exact same dress. Seems unlikely the woman of the house would wear the same clothes as the scullery girl.
Other mistake: Cherita has a speech impediment: instead of saying "shut up" she says "chut up." This is also reflected in the subtitles every time it happens EXCEPT at the bus stop, when it reads "shut up." (00:15:40)
Other mistake: The software the FBI agent is using to decrypt the "Stego-encrypted GIFs" says "ANOMALLIES FOUND; TRUE", with 2 Ls, and closes the report with a pretty worrisome "EXRTANEOUS POGRAM FOUND; TRUE." (00:32:30)
