“Casanova” was very mild for an R-rated film. I have seen films that the MPAA has rated PG-13 that contain more graphic elements than “Casanova”. Europe was very racy during Casanova’s time, but it also was controlled by the Catholic Church and their rigorous enforcement of the straight and narrow lifestyle. Jeremy Irons plays a Catholic Bishop who is after the famous fornicator Casanova. The cat and mouse games that Casanova plays with the Bishop are pretty funny and will entertain and amuse you.
Even though Director Lasse Hallström keeps the sex scenes tame, they are still too much for family audiences. The fact that Casanova sleeps with scores of women and a scene where group sex is strongly implied, should leave the family audience looking elsewhere for their adventure fix. Might I suggest “The Count of Monte Cristo?”
