CITIZEN KOCH from filmmakers Tia Lessin and Carl Deal (pictured below, left to right) may be news and will surprise you. Much of what I saw here struck me as fairly old news, though I found the film worth seeing.
ALEC to the Koch-sponsored annual "getaways," during which the rich and powerful meet and discuss their plans for America. Still, the movie seemed to me a little unfocused and not as strong as it might have been via other hands.
Netflix, Amazon Instant Video and probably elsewhere, too.
