The first shot immediately after the opening titles shows a shiny brass plaque "INTERNATIONAL EXPORTS LTD". Look closely at the reflection just visible in the bottom left of the plaque, and you'll see a man walking past. It's the film's director, Peter Hunt, making a "blink and you'll miss it" cameo appearance.

When Bond is taken to a locker room by Draco's men they pass a janitor who is whistling a very distinct tune, the tune is Goldfinger, the third official Bond film tune.

While Bond is meeting with Sir Hillary, the Bond family motto is briefly mentioned - The World Is Not Enough.

In the scene where Draco is talking to Bond, in Draco's office, look closely at the picture in the portrait frame on the bookcase, in the background. The lady in the picture is Diana Rigg's mother. (Possibly an "in-joke" by the Bond production team?)

"On Her Majesty's Secret Service" is the longest Bond film made of the series. It is both longest in terms of running time (136 minutes) and longest in terms of the time it took to shoot the movie. Filming began at Schilthorn, Switzerland, on 21st October 1968, and finally "wrapped up" at Pinewood Studios, England, on 20th June 1969 - one day short of eight months later

George Lazenby's first and only appearance as James Bond. He had said that because of the counter-culture of the late 1960s, he felt that the character of Bond will be obsolete, so he did not return for the next film.

Bond (Lazenby) rescues Diana Rigg from her attempted suicide on the beach, but then is attacked by two men. While he is busy punching it out with them, Rigg jumps into her car and drives away. Emerging victorious from the brawl just in time to see her vanish over the horizon, he mutters, "This never happened to the other fellow" - a reference to his predecessor Connery's movie successes with the other sex.

Contrary to popular belief at the time, the film was not a flop in the U.S. In fact it was the ninth most profitable film of 1970.

When Bond is in his office he takes out some gadgets. The music that plays when Bond takes out the gadgets matches the film they are from.
