Shane Carruth wowed and baffled audiences in equal measure with his ulta-low budget high concept science fiction debut Primer, but nothing would prepare people for the bizarreness of his sophomore film Upstream Colour. Upstream Colour certainly stands as one of the strangest movies of the decade - and probably of all time - but there's a subtle method to the madness on display here. As Primer demonstrated, Carruth is a filmmaker interested in posing more questions than answering them - if indeed there is an answer to this story of sybiotic parasites. Carruth shot the film himself, with many of the strangely beautiful sequences resembling something out of a David Lynch dream sequence, while the experimental editing makes this one of the strongest candidates for the best in pure cinema in recent years.
