This week the DVD Savant has a number of new reviews and articles including: Robinson Crusoe On Mars - This transplant of Daniel Defoe from a deserted island to the chilly Red Planet is a fairly impressive survival story, at least until Friday shows up along with some unlikely space slavers; Army of Shadows - Jean-Pierre Melville's taut, uncompromised story of the French resistance benefits from excellent performances from Lino Ventura and Simone Signoret; and Heat Lightning - A desert rest stop is the setting for passion and crime in this steamy Pre-code from Warner Bros. Read all this and more in this week's DVD Savant.
