15. The Lodger: A Story of the London Fog (1928)
Stars: Marie Ault, Arthur Chesney, June, Malcolm Keen, Ivor Novello
The Lodger: A Story of the London Fog, an early Hitchcock silent film clearly inspired by German expression (see: The Cabinet of Dr. Caligari), was the director's first commercial success. In it, a Jack the Ripper-esque serial killer is butchering women in London, which, unluckily for Jonathan Drew (Ivor Novello) is timed with his arrival to the city—shortly after Drew arrives, his landlady thinks he's the murderer.
It's not full-on horror, but The Lodger definitely shows Hitchcock finding himself in that macabre arena. Much like his future classics Dial M for Murder, Psycho, and Rebecca, it's an exploration of the relationship between sex and death, though demonstrated without showing much of either.
