This week the DVD Savant has a number of new reviews and articles including: Our Hospitality - Buster Keaton's first full-length comedy with one storyline is a gem of movie construction and a comedic innovation; The Horse Soldiers - John Ford's last great cavalry saga is now out in a brilliant Blu-ray transfer, restoring the 'bigness' to Ford's old-fashioned style of direction; and Diabolique - Henri-Georges Clouzot's original murder chiller packs a solid impact for viewers with the patience to fall into its icy spell. Read all this and more in this week's DVD Savant.
