On Her Majesty's Secret Service

George Lazenby takes over the most coveted role in film for OHMSS, and despite what most people told me, doesn't do too bad a job of it.
The Australia model and television commercial actor won the role by accidentally punching a stuntman in the face during his audition. As the first Bond after Sean Connery, Lazenby was always in for a hard time.
Back to the film, OHMSS gave a greater insight into the character of Bond, more than what had been offered in the past. We found he had somewhat of a softer side, but it also developed his now well-established trait of never leaving his work.
Diana Rigg puts in a great performance as Countess Tracy Di Vicenzo, arguably the best Bond girl in the entire series.
Blofeld takes on a new physical identity as he leads his team of "Angels" - a group of women who have had their memories wiped and act as his personal army.
The film features a memorable snow chase scene, complete with cross country skiing, a bobsleigh chase (and fight), and even a car down the bobsleigh track. The most obscure part of the film was to have Bond and the Countess marry at the end of the film, a decision which could've acted as the last in the series.
Thankfully, it wasn't.
