Mark of The Vampire (1935)

Directed by Tod Browning

By my estimation, one of only four times Bela Lugosi would play a vampire was in this very silly spooks-and-scares comedy.  It's a remake of a lost silent film called London After Midnight that starred Lon Chaney.  All around fairly entertaining.  Also I have to say, the bat prop they use in this movie is incredibly well done. It looks better than any of the ones used in the Dracula movies

It Happened One Night (1934)

Directed by Frank Capra

Frank Capra practically invented the now well worn romantic comedy formula with this movie.  A man and woman can't stand each other but are stuck together due to circumstantial reasons and end up falling in love.  But honestly that doesn't do this film justice because it is a very funny charming movie.  The famous scene is one where they are on the road trying to hitch a ride.  Clark Gable is trying to man'splain ride hailing technique when Claudette Colbert gives him a lesson in the power feminine allure.

The Great Dictator (1939)

Directed by Charlie Chaplin

It escaped no one that the infamous leader of Germany had a very similar appearance to one of the most popular entertainers of the day.  So what was Chaplin's reaction?  To make fun of him mercilessly of course.  Chaplin later said if he had known the true horrors of the Nazi regime he wouldn't have treated the subject as lightly as he did.  However, you have to give him a lot of credit for being one of the few voices openly criticizing the Nazis at this time.  It is a brilliantly made movie with some hilarious moments.  Some scenes are now more moving than intended knowing the ultimate fate of the Jews.

The Most Dangerous Game (1932)

Directed by Irving Pichel, Ernest B. Schoedsack

 First movie I can think of that follows the familiar story that, due to unforeseen events the central characters end up at the residence of a crazed maniac, who then chases them throughout the movie and it is eventually revealed that the circumstances that caused them to be there was in fact orchestrated by said crazed maniac.  Fay Wray is the damsel in distress and they re-used sets from King Kong!

4/5 crazed madmen say you should watch this movie.

Vampyr (1932)

Directed by Carl Th. Dreyer

Mildly eery, glacially slow vampire movie.  Largely uninteresting and forgettable.  Nosferatu (1922) is a much more interesting alternative to this vampire story.
