I have a negative example.
I was watching an old silent movie (thanks, NetFlix!), and in it, Charlie Chaplin was on railroad tracks. Behind him was the train, approaching rapidly, filling up the screen, belching smoke. But Chaplin stood there, oblivious, and only just managed to step off the tracks before the train barreled over the spot he'd been standing.
If you watch it, it makes a certain sort of sense to you, because you're "in the universe" where there is no sound. After all, you can't hear it, and he DID have his back turned, so he couldn't SEE it....
But if you let yourself THINK about it a second, you realize...Chaplin would have heard that train! Just because we, the audience, couldn't didn't mean that the guy right there on the tracks couldn't.
It was very subtle and made me appreciate the delights of the silent genre in a way I had not before even thought of.
