Perhaps even making non-gimmicky live action 3d films.

Having 3d renders of the entire film without needing green screens and a bunch of balls seems like it would have to make some of the post processing work easier. You can add or remove elements. Adjust the camera angles. More effectively de-age actors. Heck, even create scenes whole cloth if an actor unexpectedly dies (since you still have their model).

Seems like you could also save some time having fewer takes. What you can fix in post would be dramatically expanded.

Best part for film makers, they are often using multiple cameras anyways. So this doesn't seem like it'd be too much of a stretch.
