Revealing mistake: In the bar scene at the start, Del and Rodney are talking to Mike to try to get him to by a computer that doesn't work. The leaflet that Del reads off, is completely blank.
Revealing mistake: When Albert says to Rodney about his date, "Where are you taking her? Scrumping?" As he says that line, look at Del. He mouths them by accident. (00:26:40)
Yuppy Love - S6-E1
Revealing mistake: Just after Cassandra gives Rodney his coat back, she leaves the building. As she does, you can just see Rodney in the reflection in the door. He's waiting for his cue to come out of the building.
Danger UXD - S6-E2
Revealing mistake: When the dolls explode in the flat, you can tell they are being held by a member of the crew by the way they move. (00:26:30)
Chain Gang - S6-E3
Revealing mistake: When Arnie's car flashes its headlights to Del, it is obvious that the person sat in the car is not the actor playing Arnie in the rest of the episode. (00:13:25)
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.
The Unlucky Winner Is... - S6-E4
Revealing mistake: After Rodney berates Del whilst he's in the bathroom of the hotel room he and Cassandra go out to the balcony and Cassandra goes to get him a drink, Del then goes out to join him. Whilst they're talking you can see Cassandra in the reflection of the balcony door waiting for her cue to come in to give Rodney his drink.
Revealing mistake: When Rodney is asking Del if he thinks the bathroom is haunted, you can see stage lights in his spoon. (00:10:20)
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 Albert is coming through the crowd of people that Del is talking to, to go and look out, look at the extra just to the right of Albert. He forgets he should be in role and stares straight at the camera for the whole time.
Revealing mistake: When Slater asks if the baby will be named after him and Rodney gives his answer, camera shows Del and you can quite see David Jason doing his best not to burst into laughter because of Rodney's answer.
Suggested correction: After Rodney gives his answer, the camera cuts to Slater, and then back to Del. He isn't close to bursting into laughter. He only laughs when he and Rodney stare at each other after Slater has left the pub, which was certainly the original intention.
Three Men, a Woman, and a Baby - S7-E7
Revealing mistake: When Albert and Rodney are waiting in the hospital corridor, at one point it is around 2 a.m. A view out the window and reflections show that it is broad daylight.
Revealing mistake: As Del Boy is talking to Rodney and preparing his bacon sandwich a lingering shadow can be seen, being cast against the kitchen door. This shadow belongs to Uncle Albert, who is waiting for his cue to walk into the kitchen with Weetabix on his face. (00:10:55)
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: When Rodney is holding Damien, it shows a shot of it in the mirror, the next shot is from behind the mirror and he is holding him the different way round.
Suggested correction: This was during his dream, so probably plausible in those circumstances.
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.
