Billy Lynn's Long Halftime Walk director Lee Ang and one of its stars, Vin Diesel (both above), at the New York Film Festival where the film premiered last Friday. Lee shot the movie in 3D and it will be shown - in theatres that can accommodate it - at 4K resolution and 120 frames a second, surpassing any previous major film release. The film, about a young soldier returning home after a harrowing battle in Iraq, has drawn mixed reviews. Before the premiere, Lee said: "Please give this a chance. Have an open mind. Enjoy the show."
