Factual error: While discussing the death of a car accident victim with detectives, the pathologist Dr Elizabeth Rodgers takes out a french fry, seasons it with mayonnaise and eats it. She is in the morgue, wearing bloodstained scrubs. Nobody ever eats or drinks in a morgue. This is not a character error; eating and drinking in a sterile laboratory environment is absolutely forbidden and this is taught to medical and science students from day one of their degree courses. In fact she would not even have food in there in the first place.
Revealing mistake: A minute or so after the health and fitness instructer dies, we see her lying flat out on her back. If you look carefully, you can see her chest moving up and down and breathing despite being dead. (00:13:05)
Continuity mistake: When Gussie is telling Jeeves & Wooster that he gave the notebook to Sir Watkyn, in one shot, the scarf on Wooster's head changes from being wrapped around his neck to draped loosely on his head. In the next shot, it's back around his neck. (00:36:40)
Continuity mistake: In the scene where Baloo and Kit walk through the Sea Duck's cargo area to try and find who they think is a stowaway, Baloo lifts a crate of fragile crystal glasses over his head. The crate rotates between shots, judging by its red "Fragile" stamp.
Continuity mistake: When Randi is in her tent working on her thesis, the computer is on. When something hits the tent, she almost drops her computer which now has a black screen, indicating that it is off. When the werewolf rips through the tent, the computer is now back on.
