The Threepenny Opera (Germany, 1931) is set in the impoverished back alleys of Victorian London. Underworld antihero Mackie Messer (a.k.a. Mack the Knife) tries to woo Polly Peachum and elude the authorities. The sly melodies of composer Kurt Weill and the daring of dramatist Bertolt Brecht come together on-screen in this adaptation of the Weimar-era theatrical sensation.
