the other celebrated recent italian crime movie is Arrivederci amore, ciao... but I don't like it very much, not as Romanzo criminale
the book "Arrivederci amore, ciao" is great, his writer (Massimo Carlotto) has a very particular personal history and he is an excellent noir writer, some months ago I read an his book called Nordest and i found it really wonderful, perhaps the best book of the last years, i think that Arrivederci amore, ciao (the movie) could be better....
another recent movie located in 70-80's is L'odore della notte with Valerio Mastrandrea that is the real 'missing actor' in Romanzo criminale, I think it's a good movie
now is out in italian cinema "Fine pena: mai" that sounds good but i haven't seen it yet, the real life through 80's of a boss of Sacra Corona Unita that was an organization as mafia or camorra
also i read that Romanzo criminale will become a tv-serie or some tv-movies... now are working for this in Rome
