One of the challenges in writing the script Call Me by Your Name was that I had to find something concrete for the professor to do. In the book he is some kind of classics scholar. But I thought it would be interesting to make him into something of an art historian and archaeologist whose background was the classical world. It's always difficult when someone is supposed to be an intellectual. What do they do? You can't just film them sitting around and thinking all day. And that's what the business of the statues is all about.
