YMMV / The Public Enemy

  • Adaptation Displacement: Bet you didn't know it was based on a book called Beer and Blood?
  • Do Not Do This Cool Thing: The film opens with a title card explicitly stating that the studio did not seek to "glorify the hoodlum or criminal". It makes the gangster cooler, more interesting, and more important than his straight-laced brother.
  • One-Scene Wonder: If Mae Clarke is remembered today at all, it's for that one scene where James Cagney smashes the grapefruit in her face.
  • Signature Scene: Tom Powers pushing a grapefruit in his girlfriend's face.
