For a while in Jamie Meltzer's mesmerizing documentary Informant, I wondered whether subject Brandon Darby, the lefty activist turned FBI informer, was being played by an actor.

But no: It's Darby, and he's a handsome fellow, with haunted eyes blazing out of a bone structure to die for, and with a Montgomery Clift dimple in his chin. Staring straight into the camera, he testifies with the intense calm of a messiah or a madman, which all too often comes to the same thing. Among other things, this powerfully confused man is a study in American extremity.
