The Long Legs of the Law - S2-E1
Revealing mistake: At the very beginning of the episode, Leonard Pearce is waiting for the cue for his character to start looking for his teeth. He's standing in the living room, between his room and Del and Rodney's room. (00:00:25)
Revealing mistake: When everyone's back at the flat, as Del Boy is looking straight down the hallway to his and Rodney's bedroom, someone comes up to him and he turns around. When it goes from his close-up to the wide shot of everyone else the shadow of the camera reversing backwards is visible for a few seconds.
The Second Time Around - S1-E4
Revealing mistake: When Del, Grandad and Rodney Come Home to the flat after staying with their Aunt, as Del is checking the kitchen you can see Lennard Pearce standing by the door waiting for his cue. (00:26:05)
Three Men, a Woman and a Baby - S7-E6
Revealing mistake: When Albert and Rodney are waiting in the hospital corridor, at one point it is around 2am in the morning. A view out the window and reflections show that it is broad daylight.
Revealing mistake: At the end of the episode when Del and Rodney get hit by the car, Del jolts forwards slightly before we hear the sound of the crash. (00:29:10)
Revealing mistake: When Del is trying to sell those hooky toy dogs, there are some shots of the policeman walking across the street. The same clip of that policeman is played twice, only one is longer than the other (note a grey-haired man walk across the screen twice). (00:01:35)
Revealing mistake: When Denzil thinks he's going mad seeing Del cross the road, look at the zebra crossing Del is walking on. It's just a bit of carpet rolled down on the ground.
Hole in One - S4-E3
Revealing mistake: Uncle Albert is seen putting the post back through the letter box. If you watch the scene carefully, the letters appear to pull themselves through, no doubt with a helping hand from the crew.
Revealing mistake: In the Trotter's flat at the start, in some shots, you can see the mirror has been bent so you can't see the camera's reflection.
The Second Time Around - S1-E4
Revealing mistake: When Grandad is speaking strangely and telling Del that Pauline has hidden his teeth, you can see his bottom set of teeth.
Modern Men - S8-E2
Revealing mistake: When Del and his mates are in the pub, when it's Del's turn for the drinks, he gives Mike a hairdryer (really an electric paint stripper). If you notice, Del picks up the hairdryer off the floor.
Revealing mistake: When the kid steals the orange, look how the orange is conveniently placed higher than the rest to make it easier for him to pick up.
Revealing mistake: When Raquel walks into the living room after Rodney has told Del about the successful bloke, you can see a studio light on one of the pictures on the wall.
Revealing mistake: Look behind Rodney and Vicky as they enter the theatre for the Gala performance. A small crowd has gathered across the road to watch the filming.
Revealing mistake: When Del sees Denzil skating along and tells him that he's got his money (the butterfly), Denzil gives him a high five and crushes the butterfly. If you look at Del's hand when Denzil goes past him, you can see the butterfly is not crushed at all.
Hole in One - S4-E3
Revealing mistake: When the post is being posted through the door, you can see the letters appear in the letterbox and then wait a few seconds for Albert to hang his coat up before being pushed through. (00:01:00)
Revealing mistake: As Del is sitting down to watch his video, if you watch the video recorder, a false top superimposes over the real one.
Revealing mistake: When Rodney first meets his new girlfriend, watch as he says "Pleased to meet you Irene". He spits on her. Not a great first impression.
The Unlucky Winner Is... - S6-E4
Revealing mistake: When Rodney and Del are sitting on the balcony and Cassandra has gone to get Rodney a drink, if you look in the glass door, you can see Cassandra's reflection with the drink waiting for her cue to come in.
The Unlucky Winner Is... - S6-E4
Revealing mistake: In the airport scene, the same extra walks past 3 times wearing different clothes.
Suggested correction: Not necessarily a mistake. If someone is looking for something they often try to think where it could be before they start searching.
