On tonight's episode of "Elvira's Movie Macabre," the horror hostess with the mostest screens "The Satanic Rites of Dracula," Hammer's sequel to "Dracula A.D. 1972." Christopher Lee plays Drac for the last time in a Hammer film, and attempts to take over the entire world, starting with modern-day London. (Well, modern at the time. The fashions look about as quaint now as those of the previous period-set films.) Watch it at 1 A.M. on KOFY TV 20 cable channel 13.
