Character mistake: Sam encounters Marc Bolan in the club and warns him to "drive carefully", aware of Bolan's future death in a 1977 car accident. However, Bolan never learned to drive and he was actually a passenger in the fatal accident. (00:07:55)
Continuity mistake: When Sam and Gene enter the pub with the T.V., they both stand at the bar with Gene leaning one hand against the bar. In the next shot Gene is leaning on it with both hands. When the shot cuts again he is back in his original position with one hand on the bar.
Continuity mistake: Sam and Gene are discussing how to deal with Stephen Warren and having a drink. Sam holds the bottle of scotch with the label facing away from him. It immediately does a 180 degrees turn as he takes a slug from it.
Chosen answer: Sam is using the modern wording of the right-to-silence caution prescribed by legislation such as the Criminal Justice and Public Order Act 1994. In the 1970s, the wording would have been different, if it was used at all.
