I've just seen this movie on DVD and enjoyed the humor and wit. According to some Dutch and French web-pages like http://perso.orange.fr/cinefrance/1960/zazie.html Zazie is not played by 12yo Catherine but by a 9½yo Milène, what seems right to me by the looks of her, she's definitely too petite for a 12yo, age 9 or 10 seems much more likely. In the trailer she is described as a 9½yo too. Her lines seem a little too adult now and then, but bear in mind who wrote the scenario! Louis Malle was famous for breaking taboos. This movie was intended for enjoyment, like a comedy, but with a sharp view on the changing French society. Also some comments on hypocritical ways of dealing with taboos like homosexuality and "dirty old men". Funny to see the traffic congestion in Paris, already then, and the looney effects, inspired by Tex Avery.
