Vampyr

For much of the cast, this was their only film appearance since they were not professional actors. Henriette Gérard who played the vampire was a French widow, Jan Hieronimko who played the village doctor was a Polish journalist, Rena Mandel who played Gisèle was an artist's model. Even Julian West (real name: Baron Nicolas de Gunzburg) who played Allan Grey, was French-born member of Russian nobility who agreed to finance the film in exchange for the leading part. (He later emigrated to America where he became a powerful fashion journalist and mentor to designers like Calvin Klein.)

At exactly 16 minutes (in the Criterion DVD) as the camera pans right, there is a reflection in a glass window of the camera operator cranking the camera.

There is an Italian edition of this film on DVD, distributed by DNA srl, "LA STRANA AVVENTURA DI DAVID GRAY (Vampyr - Il vampiro, 1932) + NOSFERATU, UNA SINFONIA DELL'ORRORE (1922)" (2 Films on a single DVD), re-edited with the contribution of film historian Riccardo Cusin. This version is also available for streaming on some platforms.

Edited into Dr. Terror's House of Horrors (1943)
