What I like about acting on stage is immediate, live reaction from audience. Film acting largely lacks that, though there are techniques to compensate it. I'd imagine "VR film shooting" would be similar to film acting in that regard. (Except in the case that VR becomes live and bidirectional---that would be interesting.)
You could record a dinner theater-style show.
Then the audio becomes the cue for expected viewpoint. Most people turn to look at an actor speaking.
Right, recording non-proscenium theater plays would be interesting contents. I like to watch (and often perform) round- or three-sided stages in a small theater. That kind of shows are difficult to capture in traditional camera for it loses the feeling of space surrounding audience.
I wonder what this would mwan mean for all the actors who prefer stage to film. Would they shoot up in demand? What would that mean for theater in general?
