This document provides an overview of several film theory approaches, including feminist film theory, Marxist film theory, postcolonial film theory, psychoanalytic film theory, social realist film theory, structuralist film theory, and formalist film theory. It discusses key thinkers and concepts for each approach, such as Laura Mulvey's concept of the "male gaze" in feminist film theory, Karl Marx's views on class struggles and materialism in Marxist film theory, and the exploration of how meaning is constructed through codes and conventions in structuralist film theory. Overall, the document outlines several major theoretical lenses used to analyze films and their representations or themes.
