Haunted Honeymoon (1940)

Starring Robert Montgomery, Constance Cummings, Leslie Banks, Seymour Hicks, Robert Newton
Directed by Arthur B. Woods
(actor & director credits courtesy IMDB.com)

Lord Peter Wimsey, who dabbles in solving murders, and his crime novelist bride agree to give up mysteries, but find themselves plunged into one when they arrive at their honeymoon cottage.  

Bringing together American stars with a British supporting cast, the MGM studio delivers a fine mystery with many whimsical touches of humor, an appealing lead in Montgomery, and a very lovely Cummings as his partner.  The filmmakers cleverly distract us with the wealthy couple's efforts to give up crime-solving, and so we ignore the clues to the murderer's identity until Montgomery unveils him in the film's climax, and then realize they were right in front of our eyes.  It's very well-executed, and tops the cake of what was already a charming piece of entertainment.  

The Most Dangerous Game (1932)

Starring Joel McCrea, Fay Wray, Robert Armstrong, Leslie Banks, Noble Johnson
Directed by Irving Pichel & Ernest B. Schoedsack

A big-game hunter is stranded on a jungle island owned by a mad Russian count, who hunts human beings for sport, and displays their carcasses in his trophy room.

Perhaps my very favorite among the films I've seen, I've always loved this adaptation of Richard Connell's famous short story, although it's lesser known than the film it shares much of the same cast and crew with, the famed King Kong.  According to Wikipedia, this adventure was filmed concurrently with Kong on the same sets, and while it lacks that film's stop-motion special effects, it's a horror classic in its own right.  Featuring a driving musical score by Max Steiner, a memorable sinister portrayal of the villainous Zaroff by British actor Leslie Banks, great direction, and a wonderfully staged culminating chase, together all these elements contribute to making this one of the most exciting films of the early 1930s.
