Graduate in the Faculty of Political and Economic Sciences of Madrid, and after practicing for a short period as an economist, he decides to present himself to the newly inaugurated I.I.E.C., official school of cinema that opened its doors in February 1947. Zabalza passed the entrance exam in the specialty of direction for which there were only five places. His classmates in promotion were Ricardo Muñoz Suay, Jesús Franco and Juan García Atienza. In those days the students Jose Gutierrez Maesso, Luis Garcia Berlanga, Florentino Soria and Eduardo Ducay were also part of the school. Jose Maria Zabalza was a precursor in the founding of production companies in the Basque country. In 1955 he founded the production company Haz Films. With Haz Films he filmed There is also sky over the sea and Burial of an official in spring. Zabalza's professional startup style as a filmmaker was clearly and markedly within what has been called author's cinema or art house cinema. There is also sky over the sea was probably one of the first films inspired by Italian Neorealism in Spain and the first in the Basque country. And as Luis Garcia Berlanga said many times: "Burial of a civil servant in the spring, was the first film of dark humor cinema era in Spain". The difficulties with the classification of premiere and distribution, by the Francoist censorship and the General Secretariat of Cinematography and Theater, did not allow an adequate distribution of these two films. This makes the newly created production company Haz Films have to close. José María Zabalza decides to take refuge in the theater in order to continue with his artistic career. During this time he wrote and directed several plays: Camerino Sin Biombo, Autopsia de María Magdalena, Las arañas travel by night, Pensión Rosita and Ginebra for dinner. In 1963, Zabalza reached an agreement to direct his first film with a production company that is not of his property. The film had the provisional title of The noise of the silence, to later take the definitive title, and supposedly more commercial one, of I am not a murderer. The film as its first title indicated formally works with silence and long shots. Zabalza was inspired by the cinema of Ingmar Bergman and Michelangelo Antonioni, once again focusing on a style of European auteur cinema, revealing his inveterate cinephilia. Another strong feature that is shown in his films after his first three feature films is the combination of professional actors of great name with non-professional actors, people recruited on the street or among their friends. The film takes place in natural settings of Hondarribia, Irún and Zarautz. In 1964, he founded the Uranzu Films production company with his friend Carlos Serrano Tell and entered a second stage of his career as a filmmaker. With it he decides to recover a little from the difficulties of distribution suffered by his first films. His artistic line becomes lighter and commercial comedy type of film, except Camerino without a screen that is an intimate film filmed in San Sebastian in interiors with the actress Gemma Cuervo. After several films made with Uranzu films Carlos Serrano Tell decides to leave his tasks as a producer to be able to focus fully on his profession and his family life. The move away of cinema of his partner in Uranzu Films supposes to a great extent a change in the career of Zabalza that was dedicated thereafter to the cinema of genre mainly as hired director. You can consider this the third stage in his filmography. In this stage Zabalza will shoot a large number of films in genres as disparate as the Spaghuetti Western, horror movies, gangster movies or soft erotic films. Some of these films belong to the era in which international coproductions were lavished, with several films filmed in the former Yugoslavia. Perhaps the most internationally known film is the cult film that shot with the actor Paul NaschyThe Fury of the Wolfman. This moment of his filmography was not exempt from personal difficulties and for some of these films he came to be cataloged as the Spanish Ed Wood. He got to shoot three films at once or one in 24 hours and with 12 cameras, entitled The Return of the Vampires with Simon Andreu that did not have its commercial premiere, due once again to the Francoist censorship, until 1985 as The Mystery of Cynthia Baird. Zabalza as a filmmaker certainly fell into oblivion, but in recent years he has lived a renewed recognition with the publication of the book José María Zabalza: Cinema, Bohemia and Survival by Gurutz Albisu and the documentary film about his cinema and life, Director Z: el vendedor de ilusiones, de Oskar Tejedor premiered at the Festival Internacional de Cine Sitges.
