The main role of the film is played by Marta Palermo, a non professional actress of ten years old, blind since birth. She was the first one auditioned and she hardly accepted that the directors were going to meet other candidates before taking their decision. She loved the script very much and she wanted the role for herself. When Fabio Grassadonia and Antonio Piazza finally decided to give the role of Rita to Marta, they called her at the telephone saying "so... you will be Rita", and Marta immediately replied "you have not understood yes, I AM Rita already".
