El resplandor cinematográfico is dedicated to examining the work of Mexican writer Mauricio Magdaleno Cardona (1906-1986). Magdaleno belonged to a generation of writers of great scope and profound renovations. He is one of the great novelists of the Mexican Revolution. But, above all, he stood out for the creation of cinematographic books of acclaimed films such as: María Candelaria, Río escondido, Salón México, La Perla, Pueblerina, Enamorada, among many others. He is part of the cinematographic olympus of those who have made writing for film a literary genre, and is in the first place in the history of Mexican art. Because the screenplay, or film book, is also literature. It is a text that describes images, sounds, faces, emotions, movement, light and silence, on a paper made of time.Master Magdaleno taught us that every film has a complex architecture that is built from a plane called script: the buried root of the tree of cinema. It is in this often underappreciated, mistreated art of the film script that Magdaleno stood out as one of the best Mexican film writers in the history of the twentieth century.
