We are so excited for Primer director Shane Carruth's brand new Sundance movie Upstream Color. And this brand new trailer is only fanning our flame of curiosity. What is going on in this trailer? Why does Shane Carruth and his fellow actress look all banged up? What did that table do to Shane? Why the obsession with the flock of birds?

All we know about Upstream Color is from the Sundance logline, "A man and woman are drawn together, entangled in the life cycle of an ageless organism." Wild guess? Carruth is a Trill-like organism, hosting another creature in between the folds of his furrowed brow.

But what we do know is that on March 22nd, Upstream Color will get a theatrical release! So we won't have to wait too long for answers — but then again this is a Carruth movie, so maybe we'll never know.
