John Turturro's performance is one of the best I have seen on TV for years. Soft-spoken, believing in what he says, until it all goes wrong. He carries off the snub by Lindbergh at the von Ribbentropp White House ball with heartbreaking grace.
Apparently Robert Bloch was asked why he referenced Ed Gein in Psycho. He said it was because, at the time, no-one had heard of Albert Fish, killer of Grace Budd amongst others.
