Primer writer/director Shane Carruth returns with his second feature film, the sci-fi drama Upstream Color. Andrew Sensenig and Brina Palencia star as a man and woman entangled in the life cycle of an ageless organism, where their Identities become an illusion as they struggle to assemble the loose fragments of their wrecked lives. We have the trailer and poster for this unique vision. Here, why don't you watch it and see if you can figure out what's going on.
