I have all 2 entire movies now. You're right, that in Caos calmo is a really hot scene, and (I didn't know!) that was supposed to be sodomization. Now I can explain why so much scandal in Italy at that time. I read many articles of 8 years ago: Isabella Ferrari didn't say "real sex", but something like "we did it real". They were a little drunk, maybe they shoot the scene without any pillow, I mean any protection, and probably there was some "contact", but nothing more (in my opinion). You should consider: Nanni Moretti (the guy) is not fond of such a kind of scene (and is politically involved), Isabella is married (long time), had already 3 sons/daugthers, sodomization is not a simple act (it requires, you know, some preparation...). It is really impossible that happened. Once again, however, I have to underline the ambiguity there's in comment (actors, directors, producers,) about sex scenes: they say, don't say, who knows, maybe, etc I thing they do that way on purpose, to arouse audience interest.
Regarding "E la chiamano estate" tdlotslv is right: (Isabella Ferrari, 48 years old in 2012) has some pussy shot and a handjob (just a touch...) in the pants. To riassume: "Caos Calmo", despite that hot scene, shouldn't be in this blog because nothing explicit is shown. "E la chiamano estate" has only a blowjob (2 secs) of explicit. (PS: the producer of this movie is Nicoletta Mantovani, tenor Pavarotti's wife).
