This episode is about a specialty from Colonnata, a little village above Carrara, where marble is quarried. It's pork lard, which may not sound very appetizing but is beloved by Italians all over the peninsula. A little goes a long way, but savored with typical unsalted Tuscan bread, it is pretty special. And marble plays an important part.

If you go to Italy, you will want to know where to go to buy the things you need. Marika is here to tell you all about i supermercati (supermarkets) and other stores.

In this segment, we're on the set with Pasolini as he shouts directions to Totò through his megaphone, and at the same time discusses the shoot with his crew. Naturally, authenticity often means people speak over each other, so it's hard to understand what is said. Then, Pasolini is asked by a journalist about his views on neorealism and here, the speech is clearer (and interesting), so don't give up!

Camilla can't help herself and goes to the home of Mattioli's former nurse. Gaetano leaves Camilla a text message. Note that in Italy, texting while driving is now prohibited.

But he knows quite a bit about the history of the place.
