Filmmakers Beth and George Gage have brought unforgettable characters to Mountainfilm audiences — the men of the Tenth Mountain Division with Fire on the Mountain and Carrie Dann with American Outrage — and they do it again with Bidder 70. What makes this film different from their others is that the protagonist — activist Tim DeChristopher, who’s been to Mountainfilm several times — cannot attend the screening in person because he’s serving two years in prison for an act of civil disobedience in which he disrupted an oil and gas land auction. DeChristopher lost his liberty in an attempt to change a system that needs radical redirecting. In his absence, the Gages and other people in the film will attend this world premiere.
