Questions about the Flying Cameras
A lot of the POV camera shots in this movie are really outstanding, especially when we follow Oscar's spirit as it flies around the city. Some of it was done with editing, but other shots looked like the camera must have been flying, too. It was obviously literally flying in a helicopter in the night shots at the end above the city, but I'm curious about how they filmed some of the other shots.
How did they film Alex when we followed him from overhead as he was running on the street away from the police just after Oscar was shot? Was the camera high up on a crane that was driven behind Alex or maybe suspended on a cable and pulled to follow him, or what?
Also, in some interior shots when the camera floated up above people and then down again - like in the hospital, I think it was - how did they do that? Were the ceilings very high and the camera on a crane? Did they shoot all these floating camera scenes with a remote camera with no operator?
