"The idea of watching an entire film basically from one person's perspective - and not even really from their perspective, but [it's] probably the most intimately shot film that's in any of these categories. If you're not familiar with Son of Saul, basically it's a film about a Jewish guy who's in concentration camp, but he helps dispose of the bodies after they leave the gas chamber. So, you watch the entire movie looking at Saul's face and looking at his interactions with people."
