This week the DVD Savant has a number of new reviews including: Valkyrie [Blu-ray] - UA and Tom Cruise's saga of the 1944 attempt by rebel generals to kill Hitler is a darn good thriller, but one that resists adaptation into a universal audience-pleaser; Man Hunt - A British sportsman tries to shoot Hitler, and becomes the prey in a London spy chase. Walter Pidgeon and Joan Bennett star in Fritz Lang's first anti-Nazi thriller; and The Spy Factory - James Bamford is the writer and producer of this plain-facts indictment of the NSA's mishandling of intelligence prior to 9/11 -- and their later practice of overriding anti- wiretap and surveillance protections. Read all this and more in this week's DVD Savant.
