Hal Ashby (September 2, 1929 – December 27, 1988) was an American film director and editor associated with the New Hollywood wave of filmmaking.
New Hollywood, sometimes referred to as the "American New Wave", usually refers to a movement in American film history from the mid-to-late 1960s ("Bonnie and Clyde", "The Graduate" and "Easy Rider") to the early 1980s ("Heaven's Gate", "One from the Heart") when a new generation of young filmmakers came to prominence in United States, influencing the types of films produced, their production and marketing, and the way major studios approached film-making.
 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.
