The movie introduces the viewer to several key moments in the text, with special attention paid to Notorious, The Birds, Psycho, and Vertigo. It might help to read the book either immediately before or after seeing the documentary. It's impossible to imagine any contemporary, commercial film-maker being as visually and thematically complex as Hitchcock turned out to be over his 50-year film-making career. He's the Great White Whale of movies, the immensely popular and complex artist. Highly recommended.
Black Sabbath (I tre volti della paura) (1963): adapted from works by Ivan Chekhov, F.G. Snyder, and Aleksei Tolstoy by Mario Bava, Alberto Bevilacqua, and Marcello Fondato; starring Boris Karloff (Gorca/Narrator) and others: Something of a stinker of an Italian anthology horror film from the early 1960's, redubbed for English-speaking audiences. Boris Karloff is fine as both frame narrator and Vourdalak in the third segment.
The first segment actually goes pretty well until the film-makers unwisely over-use their initially effective Dead Witch Dummy (TM). The second sequence sucks. The third sequence, in which a vampire-like Vourdalak terrorizes a travelling nobleman and a family of peasants, is utterly ridiculous in its plot. It's like a training film on what not to do when menaced by the Undead. Or a cautionary tale about the plague of narcolepsy that ravaged Eastern Europe in the early 19th century. Not recommended.
Don't Breathe (2016): written by Fede Alvarez and Rodo Sayagues; directed by Fede Alvarez; starring Stephen Lang (The Blind Man), Jane Levy (Rocky), Dylan Minnette (Alex), and Daniel Zovatto (Money): Admirably tense, terse thriller set in the post-apocalyptic wasteland of present-day Detroit. The creative minds behind the solid remake of Evil Dead go with a bit less gore and grue here, though more than one scene is Not For The Squeamish.
The young actors are good as three sympathetic burglars who pick the wrong house, while Stephen Lang (Avatar's nutty Colonel) is extraordinarily menacing as the blind, buff homeowner whose house our unfortunate trio break into in search of a hidden cache of Get Out of Detroit cash. The movie may invert the central premise of classic 1960's thriller Wait Until Dark, but it's also a horrifying reimagining of The Treasure of the Sierra Madre. Brutal but never exploitative. Highly recommended.
