LONDON — U.K. indie distrib Dogwoof picked up two Sundance winning docs, “Restrepo” and “Gasland,” at Cannes.

“Restrepo,” which won the docu grand jury prize at Sundance, is directed and produced by Tim Hetherington and Sebastian Junger. It follows the deployment of a U.S. platoon in Afghanistan’s Korengal Valley and was shot between May 2007 and July 2008.

Pic will be released in the U.K. at the end of September by the ethically minded distrib after bowing in the U.S. on June 25 through National Geographic Films.

“Gasland,” winner of the special jury prize for documentary at Sundance this year, is directed, produced and written by Josh Fox, a Gotham theater director. Doc follows Fox’s examination into natural gas drilling in the U.S. and its catastrophic effects on the environment and the health of the residents of these drilling areas.

Pic will be released in the U.K. some time in early 2011.

These acquisitions are in line with Dogwoof’s social conscience: The distrib has released ethically and environmentally friendly pics since its inception in 2004, including Franny Armstrong’s “The Age of Stupid” — a story about climate change — which took more than $300,000 at the U.K. box office, and Marc and Nick Francis’ doc about the global coffee trade, “Black Gold.”
