In New Hollywood films, the film director, rather than the studio, took on a key authorial role. The definition of New Hollywood varies, depending on the author, with some of them defining it as a movement and others as a period. The span of the period is also a subject of debate, as well as its integrity, as some authors, such as Thomas Schatz, argue that the New Hollywood consist of several different movements. The films made in this movement are stylistically characterized in that their narrative often strongly deviated from classical norms.
