This is one thing Amazon does well. Pause almost anything and it will show you the actors presently on screen (with headshots, which you can click on to get more info.
Eh, that's not really anything you couldn't do with google almost as easily. I mean real multimedia. I want to pause Lord of the Rings, click on a sword, and get the passage where the sword is described in the book.
