Revealing mistake: During the riot scene, the canteen walls wobble. This is most noticeable when a prisoner is trying to pull the notice board off the wall.
Continuity mistake: Just after Warren says "we want a riot," the canteen door is already open and the prison guard is seen going through it. A few seconds later the guard is seen again banging on the door to get out.
Fletch: I haven't been so put out since my son Raymond crept back into school one night and had a prior peek at the exam papers.
Godber: Did he?
Fletch: Yes he did! And he still didn't bleedin' pass.
Trivia: Before Richard Beckinsale was cast, Ronnie Barker had suggested Paul Henry (Benny from the TV soap opera "Crossroads") for the role of Lennie Godber.
