Action adventure film

While the term "action film" or "action adventure film" has been used as early as the 1910s, the contemporary definition usually refers to a film that came with the arrival of New Hollywood and the rise of anti-heroes appearing in American films of the late 1960s and 1970s drawing from war films, crime films and Westerns. These genres were followed by what is referred to as the "classical period" in the 1980s. This was followed by the post-classical era where American action films were influenced by Hong Kong action cinema and the growing use of computer generated imagery in film. Following the September 11 attacks, a return to the early forms of the genre appeared in the wake of Kill Bill and The Expendables films.
