In 1942, Tanko returned to Vienna.; however, having lost his entire family during the war, he decided to emigrate to Brazil.

In 1948, Tanko took up residence in the city of Rio de Janeiro, contributing to the professionalization of Brazilian cinema with his diverse experience. His first work was in Cinelândia Filmes, as assistant director and screenwriter of A Escrava Isaura, an adaptation of Bernardo Guimarães' novel.

Without leaving Cinelandia, he also began to work in the Cinematographic Atlântida, where he played several roles, ultimately becoming a director. Having made some dramas that were not successful with the audience, he turned to comedies (chanchadas).
