I love long take shot (long scenes) in movies. It shows the hard work and team work. In most cases, this type of scene usually requires a wide area, but Ian Hubert's technic make difference.
Ian Hubert make this shot as experiment work, but result quite pretty good. He combine multiple technics to the scenes, i.e. green-screen card, motion tracked camera, 3D stuff. I think about something that traditional long shot technic can't do it.
Creative + Technology :)
