As if a propaganda film directed by Sir Hitch isn’t impressive enough, here comes Death Mills, helmed by the inimitable Billy Wilder (Double Indemnity, Sunset Boulevard). Wilder was hired by the United States Department of War to shoot a wake-up call for German audiences, one that laid all of the Nazi regimes evil ways out on front street. A short-form documentary, Death Mills shows stock footage of concentration camps, scored by classical music—it’s a haunting contrast. To test the importance of suitable tunes in film, watch Wilder’s heart-attack-serious film on mute with your favorite rapper’s album playing in the background. Not even Kid Cud’s dark jams would work.
