世界上最长最没意义的电影 The Longest Most Meaningless Movie in the World

The Longest Most Meaningless Movie in the World is an underground movie made in the UK that runs to 48 hours long. No actual footage was shot for the project, which instead consists entirely of outtakes, commercials, strips of undeveloped film, academy leader, and other filmic castoff material, creating a seemingly endless stream of newsreel and stock footage. Some portions of the film consist of the same commercial, repeated over and over again, for more than half an hour. Strips of 35mm still picture film are also included in the film; at times, the images are run upside down, and in reverse.

The film was produced by Anthony Scott in association with the Swiss Film Centre, London. The first public screening of the film took place at The New Arts Lab in Drury Lane, London, in the Summer of 1968. It was also screened in 1969 at Cybervironment Plus, an experimental arts festival organised by Simon Chapman, and at the La Cinémathèque française in October 1970.

Once the longest film ever made, it now holds the number four spot behind Cinématon (2010), which runs for 152 hours, Matrjoschka (2006), which runs for 95 hours, and The Cure for Insomnia (1987), which runs for 87 hours.
