Other mistake: At the very beginning of the episode, Fletcher wakes up in bed and his hair is perfectly combed.
Revealing mistake: When Fletcher and Godper are assigned to the work party and they get locked into the church, one of the prisoners, Melvin (the hippy) leans against one of the 'stone' pillars of the church, causing it to wobble.
Audio problem: The prison minibus has a deisel engine when heard from inside, but when Mr Mackay borrows it to go to the pub it has a petrol engine.
Factual error: Throughout the whole show Godber, 'Bunny' Warren, McLaren, the Prison Governor and many of the guards refer to Fletcher as a Cockney. He even identifies himself as a Cockney on a number of occasions. However, in several episodes he refers to his upbringing in Muswell Hill and in this episode he refers to his having been born there - and we see his old stamping ground in that episode when he gets a weekend's compassionate leave. Nobody from Muswell Hill would ever refer to himself as a Cockney - Muswell Hill isn't even in East London!
Continuity mistake: At the end when Fletcher returns to his cell after a weekend at home his cell is on the ground floor. All other episodes it's the first floor.
