Patrick McGoohan's character "Johnny Cousin" uses the phrase "Be seeing you" when he says goodbye to the road manager "Berger" towards the end of the movie. This is a commonly heard phrase in The Prisoner (1967), The Prisoner (2009), and was also one of McGoohan's catchphrases in Danger Man (1960) and Secret Agent (1964) .
Unusually for a film of its time, this features two highly contentious subjects. One is that characters are clearly seen smoking spliffs. The other is that there are two mixed-race relationships featured in the film - and neither of them warrants a mention.
