Now Disclosure Day, out June 12, tells the story of a planet on the brink of world war, where a furtive battle breaks out over what to do with a radical new truth: we are not alone.

The director narrates a scene from his movie that is a continuation, of sorts, of a sequence he filmed for his feature-length debut, “Duel,” in 1971.

Disclosure Day may be achingly, naively optimistic about humanity, but it also depicts shadowy conspiracies with a greater sense of cynicism than the filmmaker’s ever done before.
