"Borderline" occupies a unique place in British cinema history. Kenneth Macpherson's masterpiece was made only a year after Dziga Vertov's "Man with a Movie Camera" (1929) and it features iconic star Paul Robeson and his wife Eslanda, as well as other members from the editional board of the film journal "Close Up", such as the post H.D. (Hilda Doolittle), Robert Herring and Bryther. Heavily influenced by the psychological realism of GW Pabst and Sergei Eisenstein's montage, "Borderline" is a matrix of racial and sexual tension moving between the boundaries of black and white, male and female, and the conscious and the unconscious.
