Sleep Furiously is set in a small farming community in mid Wales, about 50 miles north of Dylan Thomas’ fictional village of Llareggub, a place where Koppel’s parents – both refugees – found a home. This is a landscape and population that is changing rapidly as small scale agriculture is disappearing and the generation who inhabited a pre-mechanised world is dying out.
The central character in the film is John Jones who, once-a-month, drives the library van around the Trefeurig community, from farm to farm, collecting and delivering books. This bright yellow van becomes both literally and metaphorically a vehicle of stories – stories which take us on a poetic and profound journey into a world of endings and beginnings; a world of stuffed owls, sheep and fire. Allied to a soundtrack by the revered electronic musician Aphex Twin Sleep Furiously has been described as 'lyrical film making at its best'.
