Roger Moore had previously played a duplicate of himself in the 1970 film The Man Who Haunted Himself (1970)
Brett Sinclair (Roger Moore) asks Danny Wilde (Tony Curtis) to pick up Sam Milford's (Bernard Lee) telephone number. Danny Wild looks in Brett Sinclair's notebook and says: "Oh it's under "M"!". Bernard Lee played 'M' in the early James Bond movies even together with Roger Moore as James Bond a couple of years later.
"Shall we, children? Tramps awaits!" says Brett to Danny and the two girls at the close of the episode. This is a reference to one of the most exclusive members' clubs in the world, Tramp nightclub on London's Jermyn Street. At the time it was a mere two years old and one of the hottest nightspots in the capital.
As well as appearing together in four James Bond films Roger Moore and Bernard Lee also appeared together in Crossplot (1969).
Judge Fulton is not in this one.
