Me siento extraña

Rocío Dúrcal abandoned filming before it was completed due to an accident she had where she broke her jaw, which made it difficult for her even to speak normally while recovering. As a result, changes were made to the script to make up for her absence. Also, back then it was custom in Spain to overdub all the actors in a movie with their own voices or with different voice actors to enhance sound quality or the actor's performance if the actor's quality was not good enough. Usually, Rocío Dúrcal, who was a competent actress, dubbed herself when needed, but since she wasn't available to return and the direct sound was not good enough for the final editing, Dúrcal's character had to be overdubbed by voice actress María Antonia Rodríguez, being the only movie where Dúrcal's voice was not heard at all.
