A collection of short films produced by the gpo film unit. The bfi national archive, in partnership with bt, royal mail and the british postal museum and archive, has curated and restored the output of short films produced by the gpo film unit from 1933 1940. The unit provided a spring board to many of the best known and critically acclaimed figures in the british documentary movement, including john grierson, alberto cavalcanti, basil wright and harry watt, alongside innovators and experimentalists such as len lye and norman mclaren. This, the first of three volumes, provides an exploration of the unit's early experimentation with sound and features the award winning 'song of ceylon' 1934 and other neglected works, many of which will be available for the first time since their original release.
