Thunderball is a 1965 spy film and the fourth in the James Bond series produced by Eon Productions, starring Sean Connery as the fictional MI6 agent James Bond. It is an adaptation of the 1961 novel of the same name by Ian Fleming, which in turn was based on an original screenplay by Jack Whittingham devised from a story conceived by Kevin McClory, Whittingham, and Fleming. It was the third and final Bond film to be directed by Terence Young, with its screenplay by Richard Maibaum and John Hopkins. The film followed Goldfinger (1964) and was followed by You Only Live Twice (1967).

The film follows Bond's mission to find two NATO atomic bombs stolen by SPECTRE, which holds the world for ransom of £100 million in diamonds under its threat to destroy an unspecified metropolis in either the United Kingdom 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 CIA agent Felix Leiter and Largo's mistress, Domino Derval, Bond's search culminates in an underwater battle with Largo's henchmen. The film's complex production comprised four different units and about a quarter of the film comprises underwater scenes. Thunderball was the first Bond film shot in widescreen Panavision and the first to have a running time of over two hours.

The film was exceptionally successful: its worldwide box office receipts of $141.2 million exceeded not only that of each of its predecessors but that of every one of the five Bond films that followed it. Thunderball remains the most financially successful film of the series in North America when adjusted for ticket price inflation. In 1966, John Stears won the Academy Award for Best Visual Effects and BAFTA nominated production designer Ken Adam for an award. Some critics and viewers praised the film and branded it a welcome addition to the series, while others found the aquatic action repetitious. The movie was followed by 1967's You Only Live Twice. In 1983, Warner Bros. released a second film adaptation of the Thunderball novel under the title Never Say Never Again, with McClory as executive producer.

Guy Hamilton was invited to direct, but considered himself worn out and "creatively drained" after the production of Goldfinger. Terence Young, director of the first two Bond films, returned to the series. Coincidentally, when Saltzman invited him to direct Dr. No, Young expressed interest in directing adaptations of Dr. No, From Russia with Love and Thunderball. Years later, Young said Thunderball was filmed "at the right time", considering that if it was the first film in the series, the low budget (Dr. No cost only $1 million) would not have yielded good results. Thunderball was the final James Bond film directed by Young.
