Featuring guns, cool explosions, and amazing set pieces, this movie type first developed in the 1970s in such films as Dirty Harry and The French Connection and became the exemplar of the Hollywood mega-blockbuster in the 1980s in such works as Die Hard and Lethal Weapon. These films often feature a race against the clock, lots of violence and a clear --often flamboyantly evil -- antagonist. Though they may involve elements of crime or mystery films, those aspects take a back seat to the action. Other significant works include Hard Boiled, Speed, Bullitt, and Rambo: First Blood Part II.
