Behold a Pale Horse (film)

Behold a Pale Horse is a 1964 film directed by Fred Zinnemann and starring Gregory Peck, Omar Sharif and Anthony Quinn. The film is based on the novel Killing a Mouse on Sunday by Emeric Pressburger, which loosely details the life of the Spanish anarchist guerrilla Francisco Sabat Llopart.

The story returns twenty years later, to a young boy named Paco Carlo Angeletti, who asks a man named Pedro Paolo Stoppa why Artiguez has stopped his guerrilla raids against the Francoists in Spain. Pedro sends Paco into France to find his uncle and Artiguez. When Paco finds Artiguez, he tells him he wants him to kill Violas Anthony Quinn, a Guardia Civil officer, for killing his father. Paco lets Artiguez know that his father was killed because he wouldnt tell the police where to find Artiguez.Meanwhile, Violas has learned that Artiguezs mother Mildred Dunnock is dying, and sets a trap at the hospital in San Martn to capture Artiguez, presuming that he will come to see his mother. In return for information about the layout of the hospital and surrounding area, Paco tells Artiguez to bump into Violas for him. ........
