As Wikipedia recalls,
The film follows Bond’s mission to find two NATO atomic bombs stolen by SPECTRE, which holds the world ransom for £100 million in diamonds, in exchange for not destroying an unspecified major city in either England or the United States (later revealed to be Miami). The search leads Bond to the Bahamas, where he encounters Emilio Largo, the card-playing, eye-patch wearing SPECTRE Number Two. Backed by the CIA and Largo’s mistress, Bond’s search culminates in an underwater battle with Largo’s henchmen. The film had a complex production, with four different units and about a quarter of the film consisting of underwater scenes.It’s been a while since I watched Thunderball. All I really remember from the film are Bond’s jet pack (a travel innovation for the near future, viewers were led to assume back then), that underwater fight scene, and the lovely French actress Claudine Auger, who played Bond girl Domino Derval. But I dug up the original trailer on YouTube today:
