Using interviews with close family, friends and collaborators, The Gospel According to St. Derek bears witness to Derek Jarman’s unique approach to low-budget film-making (his near-alchemical ability to turn the base components of film-making in to artistic gold, his placing of himself at the heart of all his work and his need to be part of a repertory company-type set-up). The Gospel… also promotes Derek Jarman’s importance as one of Britain's finest film-makers and acts, therefore, as a rally call to all would-be independent film-makers. This is the ’10 commandments of St. Derek ‘(who was indeed canonised by the Sisters of Perpetual Indulgence) on low-budget film-making.
