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)
Suggested correction: If you actually watch the whole episode you will find she didn't die at all.
Talking rubbish I think, she did die. Maybe you're confusing her with the old lady who fainted?
At what point in the show did they reveal the instructor didn't die? It was the old lady who had just fainted.
I'm a big fan of this comedy and have probably watched each episode 20 times! I struggle to recall any mention of the fitness instructor not being dead.
We Have Put Her Living in the Tomb - S2-E2
Revealing mistake: When Victor and Margaret arrive back from her goddaughter's, they find their new wallpaper has been stripped. Margaret then goes up the stairs to bed and through the arch window you can see her stop at the top of the stairs waiting for the scene to end.
Visible crew/equipment: On the train at the start, after everyone has left except Victor and Margret, you can see a boom operator reflected in the door's glass panel. You can see him and it's even more noticeable when he lowers the boom for when Victor sits down. (00:04:05)
Continuity mistake: The amount of beer in the glass that is glued to Victor's head keeps changing.
Revealing mistake: When Victor gets the glass stuck to his head, it's obvious there is a clear piece of plastic to stop the beer spilling out. This is obvious as it never goes past a certain point, but stops instantly.
Revealing mistake: At the start, the background of the country going by when on the train is very obviously a fake. It sticks out like a sore thumb.
The Man in the Long Black Coat - S2-E8
Other mistake: Eric Idle is called Dr Melvin Whale, but according to the subtitles he is called Dr Melvin Mile.
Revealing mistake: When Alfred is at the station, you can see that the flames are superimposed.
Revealing mistake: At the very start of the episode, there is some rice with a mouse in. You can tell by the way it moves that it's a machine making it move.
Deliberate mistake: In the shot where we see the cars in front of Victor's (shortly after Victor gets out of the car and gets back in when the traffic starts moving) you can see that after the white car on the right that there are no more cars even though the episode takes place in a traffic queue! If you listen to the commentary on the DVD, writer David Renwick points out the mistake and informs us that they had a limited number of cars for the shot. (00:11:25)
The Pit and the Pendulum - S4-E1
Revealing mistake: The inside of the kitchen set doesn't match the external shot of the real location when looking at the inside of the kitchen door. The studio has a flat wall with green patterned wallpaper, where the real kitchen has a cupboard, white handles and the worktop directly next to the door side.
Visible crew/equipment: When Victor and Margret are arguing at the door you can see the background is a sheet, and it moves at one point.
Visible crew/equipment: When Victor and Margret are arguing at the door, a stage light is just visible to the side of the door.
Suggested correction: No, this is not the case.
Continuity mistake: Just after the scene with Mr Foskett on the roof of the house, Margaret is seen standing in the garden with her hand over her mouth, in the shot immedietly after she is standing with her hands in front of her. (00:32:25)
Continuity mistake: If you look at the corner cabinet in the Meldrew's kitchen near to the door that leads into the living room, you will notice that in some shots there is an ornamental chicken and in other shots it changes to a different blue coloured ornament.
Revealing mistake: When Victor opens the front door to Mr Foskett and the boys, you can see that the background is actually a painting.
Only a Story - S5-E2
Continuity mistake: At the beginning of the episode Margaret enters the living room and discovers that their new wallpaper has come down. In the shot from the kitchen, the wallpaper hanging down is not visible, but in the next shot there is a piece hanging down which should have been visible in the previous shot. (00:01:20)
Only a Story - S5-E2
Visible crew/equipment: When Margaret is about to confront Victor with the truth about his reflexology, in the first shot that pans over to Margaret on the very left of the screen, a hand appears and pulls the door back. It can't be Jean as we see her leaving the room to go upstairs a few shots earlier.
Only a Story - S5-E2
Continuity mistake: When Victor puts the paper down you can see there is no crease in it. Next shot there is a crease in the paper.
The Affair of the Hollow Lady - S5-E3
Revealing mistake: When Margaret hits the lady, it is very clear she dosen't actually touch her.
