Sardinian language
How much of the dialogue was in the Sardinian language (http://en.wikipedia.org/wiki/Sardinian_language)?
Obviously when the two friends speak in what the army sergeant was a "dialect", that was in Sardinian. But the rest of it sounded very Italian. Surely the villagers would have been speaking Sardinian to one another in real life. However, I don't think they did.
This was odd, I thought.
