This category is for action films produced in the United States. Action film is a film genre in which the protagonist or protagonists are thrust into a series of events 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 the victory for the villain instead).
