Starring: Fulton Mackay, Ronnie Barker, Brian Wilde, Richard Beckinsale
Genres: Comedy
Visible crew/equipment: In "The Desparate Hours", right at the end when Barraclough is in Fletcher's cell, when Fletcher says, "I never heard nothing" you can see the shadow of the boom mic on his face.
Visible crew/equipment: In the governor's office, when Urwin tells Barrowclough that the governor was instrumental in his plan, the overhead mic is in shot at the top of the screen.
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!
Mackay: There are only two rules in this prison: 1 - do not write on the walls. 2 - You obey all the rules.
Trivia: Fletch has a teenage son by the name of Raymond who was never actually featured in the show. He did turn up in the follow-up, "Going Straight", and was played by Nicholas Lyndhurst, aka Rodney Trotter from Only Fools and Horses.
