MGM is showing tonight, as a double feature, two of the strangest, most inventive vampire movies ever made – and both of these movies reward diehard film fans, who are aware that the vampire, in cinema lore, goes back to German director F.W. Murnau’s 1922 silent classic, Nosferatu. That movie was based, in large part, on the Bram Stoker novel Dracula, a decade before Hollywood cast Bela Lugosi as the long-toothed count. In Nosferatu, Max Schrek played the mysterious, ratlike Graf Orlok – and in 2000’s Shadow of a Vampire, the firdst of tonight’s vampire films on MGM, John Malkovich plays director Murnau, and William Defoe plays Schreck. The plot of Shadow of a Vampire is the behind-the-scenes filming of Nosferatu – and its conceit is that Schreck, at the time of filming, was an actual vampire. What a clever concept, and what a wild, wonderful movie. And Shadow of a Vampire is followed, at 12:25 a.m. ET, by 1988’s Vampire’s Kiss, in which Nicholas Cage plays an Eighties book editor who becomes convinced he’s been bitten by a vampire seductress (Jennifer Beals, who’s fabulous), and begins acting accordingly (pictured, with Beals). Specifically, he starts acting, more and more, the way Max Schreck did in Nosferatu. Again, what fun…
