Watch Sadisflix. Adventure film of Spanish production that follows point by point the parameters set by other literary characters, such as "El Zorro" or "El Coyote". José María Elorrieta, director with extensive experience in western spaghetti, is in charge of the direction and the script, in this film starring a gallant who was fervid among the female audience, Germán Cobos ("La patrulla", "La vida es maravillosa"). Shot on a small budget and with no other pretense than to entertain, "El falcón de Castilla" had considerable box office success.
