Sound Recording
When you have a film shot like live theater, my thought was: How did the Sound Recording go so well?
It seems that, even when the characters are distant from the camera, the sound is very present. Typically, I would think of the boom mic being overhead, fairly near the camera.
Since the actors move far from the camera, would the good sound recording be because there were microphones stationed above the actors' paths throughout the different parts of the set, and they got recording from all of them, then mixed it in post?
