Luchador films are Mexican professional wrestling/action/science-fiction/horror films starring some of the most popular masked luchadores in Lucha Libre. The luchadores are portrayed as superheroes engaging in battles against a range of characters from spies, to vampires and Martians. These films were low-budget and produced quickly. Nearly all lucha films included fist-fighting and wrestling action sequences which were choreographed and performed by the stars without the aid of stunt doubles. The genre's popularity peaked during the mid-1960s to early-1970s. At least 150 luchador films were produced starting with the 1952 film Huracán Ramírez.
