The rise of horror films in Mexico in the 1930s started with films like El fantasma del convento and Dos monjes from the writer-director Juan Bustillo Oro. Up until about the 1950s, moviehouses were mainly showing melodramas and westerns, which caused some trouble for Bustillo Oro. His films may have been popular, but they were not necessarily welcome on the big screen. As a result, his movies were associated with wrestling shows because of the outlandish costumes and makeup and the violent nature. Lucha libre, the term for professional wrestling in Mexico, became an important part of horror films in Mexico. Writers and producers would infiltrate the spooky aspects of horror films, like vampires, werewolves, and mummies, into the lucha libre films.
