Director Denis Villeneuve chats about his latest film Arrival, which opens as 12 alien ships land on Earth. Their arrival causes chaos as the ships linger "in silence" and no explanation for their presence is provided. He discusses Amy Adams' role in the film and how her character tries to understand the nature of the aliens' visit, and the challenge he faced to design an alien that hasn't been seen on screen before. He says he wanted his aliens to have a strong, instinctive presence similar to that of whales or elephants. Finally, he talks about adapting 'Arrival' from a short story and working with screenwriter Eric Heisserer to bring it to life.
