Other mistake: Early on in this episode Regan is moaning about lawyers earning £30,000 a year and that he himself can just about afford a secondhand car, but later on in this episode he is driving a M registration ford Capri, which would have been brand new when this episode was made.
Character mistake: After Regan and co jump out the back of the police van and a punch up ensues, Brian Blessed quietly walks away to a white car to make his escape. Regan clocks this and goes after him. Brian Blessed lashes out and pushes Regan away, but growls "Carter..." instead.
Character mistake: Herbie is making an anonymous phone call to Tony Kirby arranging for him to meet Vaughan. He gives a time 3 o'clock but no location, how did Kirby know where to go when he didn't know who was making the call and no location was given? (00:41:56 - 00:42:25)
