Vampire Casts a Reflection?
In the last scene of the film, the character Greta starts screaming that the vampire casts no reflection in the mirror. When Count Orlok first walks in front of the mirror in the close-up, there is indeed no reflection. However, in the next long shot, right after Greta screams, Count Orlok walks in front of the mirror again and there is a reflection. You must look very closely.
