These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Bizarro Episode: "The Man Who Liked Ants" which features The Saint stopping world domination by ants. Seriously. A Mad Scientist breeds ants to grow in size and intelligence, believing them to be a 'purer' and more admirable life form cheated out of its glory by the evolution of fallible and in-fighting prone humanity. Templar kills the ant queen and her nest before it can hatch. It's also a weird episode, because it's one of the few times you actually see Templar afraid and briefly has the heebie-jeebies about insects for a little while following it.
Bizarro Episode: Early on, The Saint would help friends and strangers. Then he started to doing the occasional espionage job for the government. Then, in "The House On Dragon's Rock", he stops a Mad Scientist's giant ant and its eggs from taking over the world.
In one episode of the 1960's series Simon (played by Roger Moore) impersonates an MI-5 agent. The woman he was tricking even remarked that it was great to have James Bond on her side. This was before Moore made his debut as Bond.
In addition to that, Lois Maxwell (the original Miss Moneypenny) guest-starred in two different episodes during the 5th series in 1966, seven years before Moore would go on to play Bond, thus also making them working together in the Bond films an unintentional case of I Want You to Meet an Old Friend of Mine.
Values Dissonance: "The Golden Journey" opens with Simon Templar suggesting that his friend could 'cure' his fiancée's spoilt brat attitude by hitting her every now and then.
Ending Fatigue: The movie continues a full fifteen minutes after the villains are arrested and the conflict is resolved. One US TV broadcast ended the movie just moments later when Emma and Simon reunite at the country house.
Mr Fan Service: Val Kilmer in his African artist role, sliding a notebook into his pants, in a way that suggests he is wearing no underwear.
