On Her Majesty's Secret Service (1969) is the sixth spy film in the James Bond series, based on the 1963 novel of the same name by Ian Fleming. Following Sean Connery's decision to retire from the role after You Only Live Twice, Eon Productions selected an unknown actor and model, George Lazenby, to play the part of James Bond. During the making of the film, Lazenby decided that he would play the role of Bond only once.
In the film Bond faces Blofeld (Telly Savalas), who is planning to sterilise the world's food supply through a group of brainwashed "angels of death", unless his demands are met for an international amnesty for his previous crimes, recognition of his title as the Count De Bleuchamp (the French form of Blofeld), and to be allowed to retire into private life. Along the way Bond meets, falls in love with, and eventually marries Contessa Teresa di Vicenzo (Diana Rigg).
This is the only Bond film to be directed by Peter R. Hunt, who had served as a film editor and second unit director on previous films in the series. Hunt, along with producers Albert R. Broccoli and Harry Saltzman, decided to produce a more realistic film that would follow the novel closely. It was shot in Switzerland, England, and Portugal from October 1968 to May 1969. Although its cinema release was not as lucrative as its predecessor You Only Live Twice, On Her Majesty's Secret Service was still one of the top performing films of the year. Critical reviews upon release were mixed, but the film's reputation has improved over time, although reviews of Lazenby's performance continue to vary.
