Malcolm Le Grice was one of the founder members of the London Filmmaker's Co-op and one of the most important champions of experimental cinema in the UK. For nearly forty years he has worked as both a film-maker and also a critic. His recent book Experimental Cinema in the Digital Age collects his writings from the 1970s up to the present day, from the pre-digital era well into the digital one. In his artistic work, Le Grice has often looked at the often complex relations which exist between the process of projection and that of vision. It is for precisely this reason that many of his films have been conceived for projection on multiple screens, in that they are really performances or installations.
In Threshold Le Grice explores the various combinations and permutations of colours that are possibile using a cinematographic printer. The film, made using a piece of found footage, begins as simple photographic reproduction, but becomes ever more complex as the visual elements and layers of colour begin to build up. Le Grice has said about this film: "Film is, at each stage, raw material for new transformation". Conceived as a film to be projected on three screens, Threshold will be shown here in its reduced format on two screens.
