The first ever teaser trailer for Shane Carruth's latest movie Upstream Color is out. It's been many years since Carruth's mind-bending and awesome Primer. Can Upstream Color live up to its predecessor? Check it out.

Upstream Color will premiere at Sundance. Here's the official synopsis (which unsurprisingly reveals nothing about the project):

A man and woman are drawn together, entangled in the life cycle of an ageless organism. Identity becomes an illusion as they struggle to assemble the loose fragments of wrecked lives.
