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.

Sir Thomas Sean Connery was a Scottish actor. He was the first actor to portray fictional British secret agent James Bond on film, starring in seven Bond films between 1962 and 1983. Connery originated the role in Dr. No (1962) and continued starring as Bond in the Eon Productions films From Russia with Love (1963), Goldfinger (1964), Thunderball (1965), You Only Live Twice (1967) and Diamonds Are Forever (1971). Connery made his final appearance in the franchise in Never Say Never Again (1983), a non-Eon-produced Bond film.
