Bond's jetpack was actually flown by engineer Bill Suiter. He was one of only two people in the world qualified to fly it.
In the underwater scenes, where Bond encounters sharks, Sir Sean Connery was supposed to be protected by clear plastic panels shielding him from sharks in close-ups. However, the panels only extended about three feet in height and sharks could swim over them. As a result, in some scenes (notably during the pool fight at Largo's mansion), Connery got much closer to the real sharks than he wanted. Director Terence Young said in an interview that scenes used in this movie where Bond reacts in fright at the approach of a shark were miscues, in which Connery was reacting with genuine terror as a shark approached unobstructed by plastic shielding. Production designer Ken Adam build a Plexiglas partition inside the pool. The barrier was not a fixed structure, so when one of the sharks managed to pass through it, Connery fled the pool, seconds away from attack. Adam said: "He never got out of a pool faster in his life - he was walking on water."

Sir Sean Connery performed the gun-barrel sequence for the first time because of the new Panavision process used in the movie. Beginning with this movie, the sequence would be performed by the actor playing Bond in the movie.
The budget for this movie was more than the combined budgets of the first three Bond movies.
Bob Simmons: The franchise regular stuntman in an uncredited part as Colonel Bouvard, the man in drag who James Bond fights in the pre-title sequence. Before "she" gets punched, the part is played by Rose Alba, explaining why "his" legs look so good in a dress. Up until this movie, Simmons had appeared as James Bond in the gun-barrel sequence in the first three movies in the franchise. In this movie, however, Sir Sean Connery performs that moment for the first time.
Diane Hartford: The wife of millionaire Huntington Hartford in an uncredited walk-on role as a girl at the Kiss Kiss Club. She had three lines with Sir Sean Connery, with whom she was dancing, when Fiona Volpe (Luciana Paluzzi) cuts into their dance at the Junkanoo. Husband Huntington gets credited at end of the movie, for the use of his privately owned Paradise Island.
Henry Ford II: The grandson of Henry Ford appeared as an extra. Ford was associated with this movie providing a few vehicles, such as a light sky blue Ford Mustang convertible, Ford Bell 47J, and a 1965 Ford station wagon.
Charles Russhon: The military adviser and technical consultant for most of the early movies in the franchise appeared as an Air Force officer. He appeared camera right of M during the conference with all of the 00 Agents. For this movie, he also liaised with the U.S. Coast Guard and U.S. Air Force aqua-para teams to organize their participation in the movie. For the production, he also organized the Skyhook rescue equipment, and a sizable amount of underwater diving gear, valued at $92,000.
