Continuity mistake: When the girls are standing in the doorway of Anges's room, considering staying there, in the reflection of the mirror, Rosemary's hand is over her mouth, but, in the next shot, not in the mirror, her hand is over her forehead.
Continuity mistake: At the very end, the girls, Ben and Burt are celebrating with champagne, but Laura's glass isn't as full as it was in the previous shot and, if you look closely, you can see that she only pretends to take a sip.
Other mistake: At the very end, Sherry's wrist is not red, as it should be, after being rammed in the desk drawer by Laura, when she went to get her gun.
Revealing mistake: When the lawnmower man crashes his lawnmower, his right leg has some sort of protection on it; it can be seen by the cut of his pants.
Continuity mistake: About halfway through, when the girls are sitting at the dining-room table and Martin walks in with a decanter of red wine, he proceeds to fill the girl's glasses, but not his own, and yet, in the next shot, his glass is filled.
Other mistake: When the girls are driving to their new job, the instructions were "turn left when you see the post box". But they turn left and then see the post box.
Plot hole: The girls refer to Holly's owner as Mr Volker, even though they now know her owner is Mr Allbright. For plot reasons, they have to say to Sherry that Mr Volker is Holly's owner, because now she knows she's killed the wrong man, and she'll have to kill again.
Continuity mistake: When we first meet Hibby, and after the girls sit down, Hibby has her arm resting on the divider between the two benches; then, in the next shot, her arm is resting on her bag.
Audio problem: Near the end, Suzanne puts the dishwasher on, which is in the kitchen, near the long kitchen table they are all sitting around. At first, we can hear the dishwasher, not very loudly but it's there, but when they expose Suzanne as the killer, the dishwasher is all but silent even though its been running for at most 10 minutes, so it should still be noisy.
Continuity mistake: When the lawnmower man crashes his machine, he is thrown clear, but in the next shot his leg is supposed to be caught under the lawnmower.
Continuity mistake: In the beginning, the Land Rover has something on the roof, like a ladder, but not long afterwards there's nothing on the roof.
Other mistake: If Laura's sore is only on the back of her hand, why does she need a bandage that goes all the way down to her elbow?
Continuity mistake: When Laura & Rosemary pull up in the Land Rover, seeing Sam's car in the ditch, Laura's seat belt is on, but in the next shot it's gone.
Other mistake: At the beginning, Alisa is supposed to be putting cream on her husband's left arm, but, while she has a great glob on her fingers, no cream ends up on the arm.
Continuity mistake: The first time we see the land rover, Rosemary's hair is flat, with the window closed; then, suddenly, her hair is being blown around, as if the window is open to accommodate a camera.
Continuity mistake: When Laura finds the hammer with blood and hair on it, Rosemary finds the constable and tells him where the hammer is. When we first see the constable's car, it's in a ditch. But when he gets into it and drives away, it's no longer in the ditch, but beside the road.
Orpheus in the Undergrowth - S2-E2
Plot hole: At the very end, Julia calls Matt, a policeman, at Helena's place, to tell him to come and help his mother and Rosemary who are being held against their will. But Matt doesn't have a mobile, so how did Julia know he was at Helena's place, so she could ring him there and save the day? No-one knew he was at Helena's and it's the middle of the night. Matt should have been in bed asleep.
Orpheus in the Undergrowth - S2-E2
Other mistake: When Rosemary comes back from seeing her old college professor, she comes in from the garden, but Julia's place - this is where Rosemary and Laura are staying - is on the first floor; there's no access to her place from the garden. Rosemary should have gone to the front door, on the street.
Orpheus in the Undergrowth - S2-E2
Plot hole: When Jeremy is found dead from a heart attack, for some reason, the girls talk about him taking something that caused his heart attack, or someone giving him something to cause his heart attack. People have heart attacks all the time, and Jeremy had "a dodgy ticker", so there's no reason for them to only think it's a "suspicious" heart attack.
Other mistake: When Rosemary is bitten by a spider, Laura says how pretty it was, with red and black stripes on its abdomen. Problem is: we don't get to see its abdomen - Rosemary wipes it away with her hand - and all we saw was black, no red in sight.
