Alfred Hitchcock is one of the rare directors who goes beyond entertainment to offer an education in filmmaking. To watch his many movies is to become familiar with cinematic suspense at its most thrilling. No scenes are wasted in a Hitchcock production: he scrupulously storyboarded each moment of North by Northwest and Vertigo, and the unrelenting momentum of each is not lost on viewers. These two acclaimed films are among nine “masterworks” to be shown at Film Forum, in the week-long program titled “Hitchcock ’50s.” The roster includes the U.S. premiere of The Man Who Knew Too Much in a 4K restoration, as well as the lesser-known I Confess (1953) and The Wrong Man (1956). The latter docudrama, based on true events and drawing comparisons to Martin Scorsese’s Taxi Driver, shouldn’t be missed. —Jack Sullivan
