Film theory explores how film relates to reality and other art forms, as well as how viewers and society interact with film. Early film theorists in the silent era defined key elements of the medium and argued that film was a valid art form in its own right. Marxist film theory examines how films can promote Marxist ideas through techniques like montage and radical editing. Lev Kuleshov conducted an influential experiment demonstrating how editing can change the audience's interpretation of shots by cutting between an actor's expression and different contextual images.
