In the earliest days of romantic comedy, filmmakers Frank Capra (Platinum Blonde) and Ernst Lubitsch (The Smiling Lieutenant) told stories of married people falling in love with outside parties.
It’s in the former republic of Zubrowka, a mountainous European nation that seems to be a sister state of Lubitsch’s Flausenthurm (from The Smiling Lieutenant) or Marshovia (The Merry Widow).
