The Unmade films of JG Ballard [1990] [aka (I think) Moving Pictures: JG Ballard] directed by Christopher Petit.
A film essay on Ballard's fiction, and its unrealised cinematic potential, with particular reference to David Cronenberg's (yet to be filmed) Crash, featuring an interview with the director, prior to making of his film.
PLEASE NOTE:Unfortunately this second film is incomplete (the tape ran out) - I have been unable to find a running time listed anywhere, but it looks like it's between 2 and 5 mins short (the whole program of both films was no more than about 25 / 30 mins long).
