The press conference at a film festival can be a place of thoughtful reflection on a film's themes and challenges, or a place where Cate Blanchett gets asked what she'll wear on the red carpet. ("I'm going naked," she brushed off the question.) With Luca Guadagnino, you never know what you're going to get: his films are lush and transgressive, but in interviews, he's just as likely to talk about that as to go on a tangent about the beauty of his lead actor's ears. Nevertheless, the filmmaker knows when to draw the line.
