The last of the great gangster films, High Sierra ushers the genre into the forties, and the gangster himself into the role of existential antihero. With a script so good its criminal, penned by John Huston and W.R. Burnett, High Sierra also boasts Bogart at his best as "Mad Dog" Roy Earle, recently sprung from jail and hiding out in the Sierras after a new robbery-a "no exit" situation which ends in a mountain shootout. Ida Lupino, as the hard-bitten cabaret singer who falls in love with Earle, here creates a mesmerizing "supporting role" that can tame even a mad dog.
