The Cabinet of Dr.Caligari (1920)

The Cabinet of Dr. Caligari featured just all the primary elements we associate with German Expressionim:

• anti- heroic characters at the center of the story
• which often involves madness,paranoia,obsession...
• the story is told from a subjective point of view

• a primary urban setting
• the criminal underworld
• the complex architectural and compositional possibilities offered, for example, by stairways and their railings, mirrors and reflecting windows...
• the director can play stripes, angles and geometrical forms sliced from the stark contrasts between light and shadow

Dr.Caligari can be called as the first film to deal with the concept of Psychological Horror.
