The sound and picture are poor, but the entirety of Errol Morris’ A Brief History of Time is available on YouTube.
Featuring music from Philip Glass, the film is a documentary about Stephen Hawking and his ideas about the universe. Morris recently stated on Twitter:
Yes. I plan to re-release [A Brief History of Time]. (It was never properly color corrected and is one of my best films.)
The film is difficult, if not impossible, to find on DVD and isn’t available on Netflix, Amazon Instant Video, or iTunes. And as far as I can tell, the soundtrack was never released either.
