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.
