The behind-the-scenes production of On Her Majesty's Secret Service

As the sixth 007 film, "On Her Majesty's Secret Service" is also adapted from Ian Fleming's novel of the same name. When the novel came out, the 1962 "Dr. No" was being filmed. This film was supposed to be the follow-up to "Goldfinger". In 1965, the producers organized a selection event for 12 angels of death. Since the copyright dispute for the novel "Thunderball" was resolved, the producers decided to film "Goldfinger" first. "Thunderball", and then started working on this film, but the problem of finding winter locations once again put the producers into trouble, and producers Harry Salzman and Albert R. Broccoli had to use "Thunderball" instead

The director of this film, Peter R. Hunter, has a long history with 007 movies. He not only participated in the filming of "Thunder Valley" as an assistant director, but also edited several previous 007 films. After working with Michael Reed, the film's cinematographer, on "Car", Hunter was eager to become the director of the new 007 film. During the adaptation of the script, the producers wanted to be as close to the original novel as possible and strive to show everything in the novel in the film. The script of the film is indeed exactly the same as the novel, so much so that the different order affects the continuity of the plot. For example, Blofeld saw Bond in "Thunder Valley" but did not recognize Bond in this film. In the first draft of the script, Bond underwent plastic surgery in order to sneak into Blofeld's lair, which paved the way for a replacement actor, but in the end, the producers gave up this idea.

In 1967, after starring in 5 007 movies, Sean Connery announced his withdrawal. Broccoli immediately chose Timothy Dalton, but the latter thought he was too young and Not suitable for playing Bond. Broccoli later discovered Australian actor George Lazabe in an advertisement. Broccoli noticed that Lazabe had Bond's stature and charisma, right down to the Rolex Submariner watch he wore in the advertisement and the clothes he wore. The Savile Row menswear is all in keeping with Bond elements. While auditioning for the role, Broccoli believed Lazabey had the ability to embody Bond's combativeness when he accidentally punched a professional boxer in the face who was serving as stunt coordinator. In the end, Lazabey got a contract to star in seven 007 movies, but his agent Ronan O'Lasiri warned him that Bond would become a relic of the 1970s, so Lazabey decided to give up starring in 007 movies after the film was released. .

The film started shooting on October 21, 1968. The main filming locations include Bern, Switzerland and Pinewood Studios in the UK. Due to the low snowfall in Bern that year, it was not conducive to filming action scenes on the snow. Therefore, the producers once considered changing the location, but the spare location was occupied by "The Runner", which tells the story of the ski legend, so the crew had to give up. While the scenes at Blofeld's headquarters were being filmed, the Piz Gloria revolving restaurant on the summit of Schilthorn was under construction, and the producers had to fund the electrical system and aerial cableway needed for filming. The alpine skiing scene featured a number of professional skiers, and the crew used a variety of complex filming techniques to complete the scene, including handheld cameras carried by stuntmen, aerial photography and the helicopter firefight scenes used in "Thunder Valley" The parachute sling system designed by architect Johnny Jordan can be viewed from any angle at a height of 18 feet.

The avalanche scene in the film was supposed to be shot with the assistance of the Swiss military, which uses blasting to eliminate avalanche hazards every year. However, the location chosen by the crew had an avalanche just before the filming started, so the special effects department had to use documentary footage and Salt was used to composite the avalanche scenes and stuntman action scenes were added in post-production. When filming the scene in which Bond and Tracy break into a car race to avoid being chased, the crew poured an ice rink on an out-of-service airstrip to complete a large number of close-ups. Diana Rigg and Rachel Zabe had to do most of the driving scenes himself.
