Unless you're 100 years old, a time traveler, an art expert, or all of the above, you may have missed the subtle visual gag that happens when Bond enters No's lair for the first time. Inside No's living room (or should we call it a dying room), Bond notices a Goya in the corner. No, not a can of black beans, but a Francisco Goya portrait of the Duke of Wellington.

Why is this funny? Because the real life painting had been recently stolen when the movie was filmed. The joke is that No is the culprit. A missile saboteur and an art thief? He truly is a criminal mastermind. (Source)

If you're on Jeopardy! and the clue is "The first actor to portray James Bond" don't answer "Sean Connery." Not because that isn't in the form of a question, and because we all know that Connery has been banned from Jeopardy! but because "Who was Bob Simmons?" would be a much more accurate response.

In the gun barrel sequence that opens Dr. No, it is stuntman Bob Simmons, not Connery, who fires his gun straight between our eyes. Ouch. (Source)

Ian Fleming lived in Jamaica, where much of Dr. No was filmed. His house there was called Goldeneye, a name that should be familiar to Bond fans. Record label guru Chris Blackwell bought the property from Fleming's estate in 1976. It has since been transformed into a resort hotel. Do you think they get sick of martini jokes at the bar? (Source)
