This return to folklore was followed by similar performances on film, including Rapsodia gaucha (1932), Ídolos de la radio (1934, memorable also for a duet between two standards of tango, Ada Falcón and Carlos Gardel), and the western movie-styled Fortín alto (1941), where he was featured with Agustín Irusta and a then-unknown Edmundo Rivero.
