Neither the press nor public screenings have yet begun, but indieWIRE reports that there have already been two sales here at the Sundance Film Festival. Up the Yangtze, a much-buzzed-about documentary by Yung Chang about the construction of a super-sized hydroelectric dam on the the ancient river and its effects on the lives of those living alongside it, has been acquired by Zeitgeist for release in April. Meanwhile, the festival’s closing night film, the Crosby, Stills, Nash and Young concert film CSNY Deja Vu, has been picked up by Fortissimo.

In other news, the Spout team is in Park City and ready, as our banner ads promise, to crash Sundance. We’ll start posting reviews late tomorrow, but check back later today for the first installment of our video coverage of the fest, produced by Ronnie Bronstein and Joe Swanberg of Butterknife.
