Could there be a better medium for the study of surveillance than video itself? Just who's watching whom is the question posed (then answered) in Aron Ranen's documentary on television evangelist Reverend Peter Popoff and his Miracle Ministries (read miniseries), on-camera faith healings attended by hundreds, observed by millions. They bring their cancers and their hernias, their coronaries and their incurable arthritis to Popoff for a shock of the healer's hand ("throw away that walker," he screams, "take a few steps to make the devil mad"). Popoff must be a vessel of the Lord, for he possesses an uncanny knowledge of his helpless flock, from their names and addresses to their precise illnesses; this is his power, and his hold. Ranen was already fascinated by the Popoff phenomenon, already part way through the making of his documentary, when he discovered the radio transmitter through which Popoff's wife, watching the proceedings from backstage, communicates to her Petey, supplying him with the details necessary to make a prophet profit. Ranen devoted the rest of his project to exposing the million-dollar fraud, but got some surprising responses from his audience. Love lingers long, it seems, even for an electronic deity. After all, as the Reverend Popoff asserts to Ranen the infidel, "Somebody has to do God's work."
