Favorite Movies by Decade (1920s)

Because I have enough favorite old movies to fill a book, I thought I'd start listing the best ones by decade. To me, the 1920s really defined what I know as film today. Storylines were starting to thicken and become more complex than before, Hollywood was flourishing and "movie stars" were really becoming a "thing." So I'll start there.
  1. Nosferatu (1922)
  2. The Lodger: A Story of the London Fog (1927)
  3. Sherlock Jr. (1924)
  4. The Cameraman (1928)
  5. The Cabinet of Dr. Caligari (1920)
  6. The Freshman (1925)
