Video Nasty - S5-E5
Visible crew/equipment: When Albert is going on to Rodney about how he was "poncing around at his art college", just above their heads, a boom mic pops into view and then moves back. (00:04:35)
Visible crew/equipment: When Del says he wants to sit down and for Rodney to do the talking, a boom mic can be seen at the top of the screen. (00:28:50)
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.
Other mistake: At the end, Rodney is looking at a map to see where Del ended up. But he didn't know where he had landed at this point so there was no point.
Continuity mistake: At the time Damien appears in the lounge with a baseball cap on, asking Rodney if he wants to play war, the shot shows him with his cap slanted to the left, next shot it's to the right and finally it ends up being straight on his head. (He was obviously quite fidgety behind the scenes).
Visible crew/equipment: When Del asks Mike if the pub is getting decorated and Mike says "in the near future", a boom mic is visible at the top of the screen. (00:26:40)
Visible crew/equipment: When Del goes back to the bar after realising that Debbie is his, in the top left of the screen, a shadow of a boom mic can be seen moving away near the "Carlsberg" sign.
Modern Men - S8-E2
Continuity mistake: While Del and Rodney are arguing over the Trotter Crash Turban, the end of the scarf attached to the helmet keeps changing position. In one shot it is behind Rodney's back, then in front of his chest, and then behind his back again.
Continuity mistake: When Boycie is playing with his new satellite dish, Marlene comes into the garden with Tyler in a pram - watch the pram switch backwards and forwards as they are having a conversation.
Audio problem: When Del is in the flat telling Grandad about him losing to Boycie in the pub, he says "only genuine weight watcher in London" however he doesn't say the word "genuine" but "only provo weightwatcher" which was obviously a topical gag at the time.
If They Could See Us Now...! - S9-E1
Visible crew/equipment: Just after Rodney throws the phone on the couch after talking to Mickey Pearce, Cassandra comes out of the bedroom. At the top of the screen, a boom mic is visible for a split second.
Strangers on the Shore - S9-E2
Deliberate mistake: When Del, Rodney and Boycie first arrive in France, there is a side view of the white van they are in and it is clear that the driver is definitely not David Jason.
Visible crew/equipment: Just before the two women look over at Rodney and Del when Rodney tries to tell Del they are looking, a boom mic can be seen at the top of the screen. (00:26:40)
Strangers on the Shore - S9-E2
Plot hole: If Lenny Corby was fitting gas fires in Boycies house, then wouldn't Del notice him there while he was cleaning the cars? He must be there at the same time because he tells Rodney about it on the same day as he was at Boycies.
Audio problem: When Del, Rodney and Grandad are in the cottage, Del is scared to open the door. Rodney says "Well go on then Del, there's nothing to be frightened of now." There is a shot from behind Rodney when he begins to say this. Look closely at Rodney's mouth when he starts to say this; his lips aren't moving.
Visible crew/equipment: Near the start, as Denzil drives away after seeing Del in a traffic jam, as you see the three-wheeled van, a boom mic can be seen reflected in the windscreen.
Visible crew/equipment: When Mr Chin is telling Rodney about the phone call he received from the health inspector, in the very top right hand corner, a boom mic is visible.
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.
Continuity mistake: In one episode, Del tells Rodney that he was born 13 years after him. Yet in this episode, when looking at the picture, Rodney says that Del is 15 and that he hadn't been born at the time the picture was taken.
Continuity mistake: Near the start when Albert is plating up the takeaway, you see him beginning to remove the lid from the takeaway. In the next shot however, the lid is completely off. The change in shot is immediate and there is no way that Albert could have moved it in that time.
Chosen answer: An apparent long string of illnesses.
