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.

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.

The film opens in a cave with a close-up of Juan Chávez's (Luis Aguilar) silver-plated revolver as he glances at a "Wanted" poster that offers a reward, dead or alive, for his capture.

There, he enters a bar called "La Patrona", whose bartender is Carmen (Lola Beltrán) who is infatuated with Juan.

She serves him something to drink, and they converse, as a next scene focuses on a beautiful woman named Rosa (Flor Silvestre) who sings the song "Cariño bonito" as she waters her geraniums and watches her birds.
