Audio problem: During the first scene of this episode, (the scene with Rodney and Cassandra in bed) there is a distinct echo on the soundtrack. (00:05:00)
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.
Visible crew/equipment: When Cassandra is on the phone to Del at the start, a boom mic shadow is visible.
Visible crew/equipment: After Albert has filled up the baby bottle with the proper water, Myles, Rodney, Del and Albert are all back in front of the shed. In one of the shed windows, a boom mic can be seen moving around.
Other mistake: After Del-boy is finished filling the first set of water bottles with the hose, he moves the rig and sets up some new ones. Now, when he pours, the water doesn't go into the bottles, but rather pours over the side. Despite this, Del continues working as though everything is fine. (00:43:45)
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)
Continuity mistake: After Rodney tells Del about Miles in the flat, as he says 'I wish I kept my mouth shut now', he sits on the sofa with his arms folded. Almost immediately after, when the shot changes to show Raquel walk in, he is now lounging on the sofa with a newspaper. He couldn't have changed his position that quickly.
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.
