In which film did George Lazenby make his only appearance as James Bond?

Lazenby was cast as "James Bond", despite his only previous acting experience being in commercials, and his only film appearance being a bit-part in a 1965 Italian-made Bond spoof. Lazenby won the role based on a screen-test fight scene, the strength of his interviews, fight skills and audition footage. A chance encounter with Bond series producer Albert R. Broccoli in a hair salon in 1966, in London, had given Lazenby his first shot at getting the role. Broccoli had made a mental note to remember Lazenby as a possible candidate at the time when he thought Lazenby looked like a Bond.

To get the role Lazenby spent his last pounds acquiring a tailor-made suit from Sean Connery's tailor, which was originally made for Connery, along with purchasing a very Bondish-looking Rolex watch.

Lazenby quit the role of Bond right before the premiere of his only film, On Her Majesty's Secret Service (1969), citing he would get other acting roles, and that his Bond contract, which was fourteen pages thick, was too demanding on him.
