Since the 1960s, film theory has undergone rapid development as an academic discipline—to such an extent that students new to the subject are quickly overwhelmed by the extensive and complex research published under its rubric. “Film Theory in the United States and Europe” presents a broad overview of guides to and anthologies of film theory, followed by a longer section that presents an historical account of film theory’s development—from classical film theory of the 1930s–1950s (focused around film as an art), the modern (or contemporary) film theory of the 1960s–1970s (premised on semiotics, Marxism, feminism, and psychoanalysis), to current developments, including the New Lacanians and cognitive film theory. The second section ends with a very brief overview of film and/as philosophy. The article covers the key figures and fundamental concepts that have contributed to film theory as an autonomous discipline within the university. These concepts include ontology of film, realism/the reality effect, formalism, adaptation, signification, voyeurism, patriarchy, ideology, mainstream cinema, the avant-garde, suture, the cinematic apparatus, auteur-structuralism, the imaginary, the symbolic, the real, film and emotion, and embodied cognition.
