When writer and academic John Hull became totally blind in 1983, he began keeping a diary on audio-cassette. Over three years, he recorded more than 16 hours of material – a unique testimony that excavates the interior world of blindness. Notes on Blindness is a feature film based on these audio recordings, interwoven with interviews with John and his wife Marilyn, embedding documentary elements within cinematic interpretations and textured sound design. Channel Editor of BBC Four, Cassian Harrison talks to writer-directors Peter Middleton and James Spinney, and also John’s wife Marilyn, about taking the viewer on a journey deep into what John calls “a world beyond sight”.

This session is not for broadcast. The film broadcasts on Storyville, BBC Four in early 2017.
