OP, I think you would get better, more detailed answer to your theater/IR/PS questions in the individual Stanford/Cal threads. You’ll find them in the Colleges and Universities forums.
Another big thing for you to think about is the Core curriculum at Chicago. It makes for a very different intellectual experience than Stanford’s, which doesn’t have it.
Frankly, with all due respect to Stanford, if it’s intellectual breadth and rigor that intrigues you, Chicago’s the place.
