You Only Live Twice is a 1967 spy film and the fifth in the James Bond series produced by Eon Productions, starring Sean Connery as the fictional MI6 agent James Bond. It is the first Bond film to be directed by Lewis Gilbert, who later directed the 1977 film The Spy Who Loved Me and the 1979 film Moonraker, both starring Roger Moore. The screenplay of You Only Live Twice was written by Roald Dahl, and loosely based on Ian Fleming's 1964 novel of the same name. It is the first James Bond film to discard most of Fleming's plot, using only a few characters and locations from the book as the background for an entirely new story.

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.
