John and Yoko's film partnership began as spring became summer in 1968, shooting two films in a single afternoon in the garden of John's house 'Kenwood' in Weybridge. The first film opens with a series of white caption cards with black lettering; "FILM NO.5 by YOKO ONO", "STARRING JOHN LENNON", "Camera: WILLIAM WAREING Sound: JOHN LENNON Light: GARDEN", "MUSIC by JOHN LENNON Instruction: bring your own instrument.", "PRODUCED by APPLE FILMS". What follows is a super slow motion 52 minute portrait of John's face in varying states of expression. A special high-speed camera had been used to film John sticking out his tongue, wiggling his eyebrows and breaking out into fleeting smiles as it captured 20,000 frames per minute, the soundtrack was provided by the background noise in Weybridge. Yoko had initially considered making Number 5 four hours long, but this was considered impractical. Even at just under 1 hour's length, it was considered overlong by most members of the audience at the film's screening at the 1968 Chicago Film Festival and after thirty minutes, more than half the audience had left the cinema. Film no.5 has since become better known as Smile.
