In the film, Bond is dispatched to Japan after American and Soviet crewed spacecraft vanish mysteriously in orbit, each nation blaming the other amidst the Cold War. 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. 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 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.
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.
