The action film is a film genre in which the protagonist or protagonists are thrust into a series of challenges that typically include violence, extended fighting, physical feats, and frantic chases. Action films tend to feature a resourceful hero struggling against incredible odds, which include life-threatening situations, a villain, or a pursuit which usually concludes in victory for the hero (though a small number of films in this genre have ended in victory for the villain instead).
This genre is closely associated with the thriller and adventure genres, and they may also contain elements of spy fiction.
