Isaac Julien documentary Derek is a beautiful collage of his old films, an interview (by Colin McCabe directed by Bernard Rose), and rare home movies. It's also a touching letter narrated by Tilda Swinton (who was a long-term collaborator of Jarman's) and serves as proof that the British film industry needs mavericks and talent like Derek Jarman to give us challenging art / films. There's been nobody else like him, and as tastes shift, his work may become forgotten and impenetrable. I've read several of his published diaries so it was great to have the extra context through this documentary.
Derek also works as a gateway to his life and those who still celebrate his work. This was directed and edited by his contemporary Isaac Julien, another great Gay filmmkaer who never seems to make films anymore.
Recommended.
