There is a cheeky inference that Patrick MacNee's bowler-hatted spy character referred to as 'S' is in fact John Steed, the character he famously played in the 1960's TV series "The Avengers". As well as dressing and acting like Steed, the final scene sees him excusing himself to greet a slim brunette in a jumpsuit, who looks not unlike Steed's old Avengers partner Emma Peel.
