Continuity mistake: When the police are interviewing people about Mr Volker's death, the girls are talking to the lawnmower man, who turns the ignition on and releases the brake, but in the next shot he reaches down to release the brake, despite having already done it.
Continuity mistake: Just before the girls leave Helena's, Laura wants to try out the new lights, but when she turns them on - there are 7 of them - they all blow, but 15 bulbs blow, not 7.
Continuity mistake: The first time the girls park outside Helena's place, they park further away from Helena's red door, as does the motorcycle in front of them - both of them park outside a blue door. But when Helena opens her red door, the Rover and motorcycle are right outside.
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.
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.
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: All the times the girls have visited Mr Allbright's rooms, they've had to press the intercom and get buzzed in. But on the last visit, Rosemary just walks in without waiting to be buzzed in.
Plot hole: The first man to be killed is a psychiatrist - "a very private man". So, if he was "very private", how did the "hip man" know if he did or did not have any psychotic patients who would want to kill him? He wouldn't.
Chosen answer: Maybe she thinks she's so old that she'll be back in the mortuary soon, so why go home?
