Action Film

Action film is a film genre where one or more heroes is thrust into a series of challenges that require physical feats, extended fights and frenetic chases. They tend to feature a resourceful character struggling against incredible odds, which may involve life-threatening situations, an evil villain, and/or being pursued, with victory achieved at the end after difficult physical efforts and violence. Story and character development are generally secondary to explosions, fist fights, gunplay and car chases.

While action films have traditionally been a reliable source of revenue for movie studios, relatively few action films garner critical praise, mainly because of their two-dimensional heroes or villains. Nevertheless, Hollywood has been making more action films than ever, in part because advancements in CGI have made it cheaper and easier to create action sequences and other visual effects that required professional stunt crews and dangerous staging in the past. However, audience reactions to action films containing significant amounts of CGI have been mixed, and films where computer animation is not believable are often met with criticism.

While action has long been an element of films, the "action film" genre began to develop in the 1970s. The genre is closely linked with the thriller and adventure film genres, and it may sometimes have elements of spy fiction and espionage.
