Count Orlok is the main antagonist of the famous 1922 German classic silent horror film "Nosferatu: A Symphony of Horror".

Orlok is one of the most iconic monsters of classic horror, rivaling Dracula, Godzilla, Frankenstein's Monster, and The Wolf Man. In this regard, he is also notable for being more faithful in many ways to the traditional representation of vampires in folklore, being a hideous demonic creature rather than an attractive tuxedo-clad gentleman.

He was portrayed by Max Schreck (born Friedrich Gustav Maximilian Schreck (6 September 1879 – 20 February 1936).
