Luchador films (or Lucha Libre 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 in and out of the ring which were choreographed and performed by the stars themselves 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.
