'The Public Enemy' (1931)
"Along with Little Caesar and Scarface, Enemy was one of the first gangster movies ever made, and it has that classic James Cagney scene where he squashes a grapefruit into Mae Clarke's face. Most movies from this era were very quiet – though I guess King Kong was an exception. There was still a theatrical element to the filmmaking process. There wasn't a big score throughout the movie, but those things would become normal elements by the end of the 1930s. The early 1930s movies were just a bit quieter and very, very intense. It really makes you appreciate the beginnings of this genre."
