Bullets or Ballots (1935) is a Warner Bros. corporate crime police detective gang infiltration classic from the pre-film noir years.
Starring the star of the show Edward G. Robinson, star of many Warner Bros. and other gangster films over three decades, perfectly paired with Humphrey Bogart, very much the rising star, in the first of five films the pair made together over the next twelve years.
That film noir charts multiple social, criminal, political, psychological trends in American society is one of its fascinations and why we're here.
