By the late 1960s, Sean Connery had grown tired of the role of Bond, after 5 films, and a search was made for someone to replace him. The producers chose George Lazenby, a relatively unknown Australian actor, on the strength of various screen tests.
In the movie, Bond is on the trail of Ernst Blofeld, his opponent from several of the prior films, yet again. During the course of his investigations he comes across Tracy, a spoilt rich girl whose father is the head of a huge European crime syndicate. Sensing that he may be able to discover Blofeld’s whereabouts, Bond agrees to spend time with Tracy in exchange for information. Blofeld is hiding in yet another spectacular hideout – a research laboratory on top of a Swiss Alp. Apart from working on an evil program to wage bacteriological warfare on the world, he is also under the impression that he might be related to royalty. Bond poses as a genealogist (which means wearing a kilt!) and tricks his way into Blofeld’s hideout. After romancing various women, Bond is discovered by Blofeld and imprisoned in the room housing the cable car mechanism.
Bond of course, finds it ridiculously easy to escape by hanging precariously from the cables, and then escapes from Blofeld’s hideout by skiing down the mountain, in hot pursuit by Blofeld and his men. Bond accidentally runs into Tracy who is spending Christmas Eve in the nearby village. Tracy and Bond escape their pursuers once again, on skis and by car. At one point during their escape, Bond, who until now has been a confirmed bachelor, surprises even himself and asks Tracy to marry him! However, Blofeld triggers an avalanche and kidnaps Tracy, while Bond manages to elude him. With the help of Tracy’s father, Bond goes back to Blofeld’s hideout in a helicopter to kill him and rescue Tracy. This is a good excuse for Blofeld’s base to spectacularly explode, as well as have an exciting bobsled chase.
