In the film some roles required nudity, so actresses were required to strip completely naked during the audition. Director Jesús García de Dueñas recalled that, "There was an essential condition and that was that those who were chosen had to be naked in many scenes, since the film was shot - as was customary at the time - in double version. We had to proceed to those 'casting' tests, which I have always disliked very much, of receiving the candidates in an office and asking them, without further ado, to take off their dresses. A lot of actresses from the 'uncovering' era passed through there, but neither the producer nor I liked any of them because, apart from the nudity, they had to have a certain acting ability."
