Prolific Spanish director and screenwriter José Antonio de la Loma entered cinema as a script writer for producer Ignacio Iquino the same year he published his first novel, Sin la Sonrisa de Dios/Without God's Smile (1951), based on his experiences as a teacher in one of Barcelona's poorest quarters. In 1955, director Julio Salvador adapted the story into a film of the same title. Loma continued working with Salvador via Laurus films through the decade's end. In 1960, Loma founded his own production company, P.C. Java, and through it produced Le Bourreau Attendra/The Hangman Waits. During the '60s, Loma worked on numerous films as a writer, director, and sometimes assistant director, often without screen credit. In 1971, Loma founded the Zodiáco production company; he founded a new company, Golden Sun, S.A., in 1987.
