Nosferatu

In 1838, Thomas Hutter lives in the fictional German city of Wisborg. His employer, Knock, sends Hutter to Transylvania to visit a new client named Count Orlok. Hutter entrusts his loving wife Ellen to his good friend Harding and Harding's sister Annie, before embarking on his long journey. Nearing his destination in the Carpathian Mountains, Hutter stops at an inn for dinner. The locals become frightened by the mere mention of Orlok's name and discourage him from traveling to his castle at night, warning of a werewolf on the prowl.

The next morning, Hutter takes a coach to a high mountain pass, but the coachman declines to take him any further than the bridge as nightfall is approaching. A black-swathed coach appears after Hutter crosses the bridge and the coachman gestures for him to climb aboard. Hutter is welcomed at a castle by Count Orlok. When Hutter is eating dinner and accidentally cuts his thumb, Orlok tries to suck the blood out, but his repulsed guest pulls his hand away. Read more on Wikipedia.
