Silence used in film

As in some bit of our film we are using silence to build pressure amongst audience members we decided to look how horror films can still have scary elements without having sound.
This is 'The Haunted Castle 1896 Silent Film' that the  early Geoge Melies filmed.

Le Manoir du diable (English: The Haunted Castle) is a three-minute-long French film directed by Georges Méliès. The film contained many traditional pantomime elements and was intentionally meant to amuse people, rather than frighten them. Nonetheless, it is considered to be the first horror film.

In English, this film has been known as The Haunted Castle, The Devil's Castle, The Devil's Manor, and The Manor of the Devil. It was released on Christmas Eve, 1896, at the Theatre Robert Houdin, 8 boulevard des Italiens, Paris.

It is a silent film but also was known to frighten people at the same time; concluding not all scary films need sound.
