This week the DVD Savant has a number of new reviews and articles including: Monty Python and the Holy Grail - Sony's new disc of the Pythons' funniest film gives the wild comedy a terrific HD transfer; an excellent set of extras does the rest; The Big Heat - Fritz Lang's furious film noir cop saga sees Glenn Ford as a hell-bent avenger out to bring down an entire syndicate for the death of a loved on; and The Odessa File - Jon Voight disguises himself as an older SS sergeant to help track down a Nazi war criminal. Read all this and more in this week's DVD Savant.
