The document discusses the use of lighting and shadows in four vampire films: Nosferatu, 30 Days of Night, Let the Right One In, and Only Lovers Left Alive.

Only Lovers Left Alive takes place mostly in a dark apartment. Overall, the document concludes that vampire movies generally employ low-key lighting, shadows, and dark décor.
