Formalist film theory analyzes the technical elements of a film like lighting, editing, sound and how they work together to create effects and communicate ideas to the audience. It looks at how individual elements or the synthesis of multiple elements like editing, shot composition and music in Sergio Leone's films build tension. Formalism embraces both ideological and auteurist criticism by focusing on style, either how socioeconomic pressures influence a style or how directors put their personal stamp on material. Alfred Hitchcock is cited as an example of an auteur with a distinct style seen in his editing, camerawork and themes.
