Diary of the Dead is a film that tries to get a physiological reaction through the use of fear and shocking one's audiences.
 Directors developed a theory of montage, beginning with Eisenstein and the complex juxtaposition of images in his film Battleship Potemkin
 Film production can, therefore, take as little as one person with a camera (or even without a camera, as in Stan Brakhage's 1963 film Mothlight), or thousands of actors, extras, and crew members for a live-action, feature-length epic
