El revólver sangriento ("The Bloody Revolver" in English) is a 1964 Mexican western-drama film directed by Miguel M. Delgado, and starring Luis Aguilar, Lola Beltrán, Flor Silvestre, Emilio Fernández, Manuel Capetillo, Antonio Aguilar, and Irma Dorantes, as credited in the film's theatrical posters. The lead actors were credited in an unusual "rigorous appearance on the screen" style, where the film's main characters are not ordered by importance, but by on-screen appearance. Written for the screen by Alfredo Salazar, the film was a production of Cinematográfica Calderón and follows the account of a silver-plated revolver, which has a deadly curse and falls on the hands of different men.
