El ojo de vidrio ("The Glass Eye") is a 1969 Mexican revolution-epic film directed by René Cardona Jr., starring Antonio Aguilar, Flor Silvestre, Manuel Capetillo, Eleazar García, Alejandro Reyna and Guillermo Rivas. With a backdrop of the Mexican Revolution, the film recounts the story of former horse wrangler and bandit Porfirio Alcalá y Buenavista who becomes the subject of a popularly known "corrido" along with his four cousins, after being notoriously heroic for raiding rich landlords and helping the poor. Being each notable for having one eye as the result of an injustice, the five heroes meet two townswomen and a theater actor who helps them disguise for their various raids. As their last raid attack, they take vengeance to the man who caused their tragedy, and evade revolutionary troops who call for peace after Porfirio Díaz resigns and is exiled.
