This week the DVD Savant has a number of new reviews and articles including: Thor: The Dark World - Great action, costumes and particularly good character turns prop up a familiar tale of Royal Good versus "Dark Elf" evil; Khartoum - King of the costumed historical heroes, Charlton Heston stars in Basil Dearden's huge epic which shows massive armies clashing in the desert and assaulting a beseiged city; and Dusty & Sweets McGee - Never appreciated when new and as about as obscure as a 1971 movie can get, Floyd Mutrux's tale of heroin junkies trying to survive in sunny Los Angeles is a portrait of misery, paranoia and waste. Read all this and more in this week's DVD Savant.
