Among the actors were also the future young musicians Massimo Varini, Eros Cristiani and Michele Monestiroli.
Cri Cri is divided into two seasons: in the first, Cristina begins, together with Steve, Michele and Andrea (who will take the place of Marco) the internship in the clinic, while the second season will take place in the hospital with curious but very nice characters and in the meantime all the friends try to make money but end up putting us back until in the last episode everything is fixed for everyone.
The theme song of the show is called Cri Cri, written by Carmelo "Ninni" Carucci and Alessandra Valeri Manera, and is sung by Cristina D'Avena herself.
Within the series, before the final theme was held there were various sketches and commercials including The Thousand and a Fairytale, English junior and Exploring the Human Body.... His album Cri Cri was released, which contained all the songs interpreted in the series.
In December 2010 the album was reissued for the first time on CD inside the box set Arriva Cristina Story, a 4-disc box containing the reissues of the soundtracks of the four Italian production shows inspired by the character of Cristina D'Avena.
