What's the best short subject to show off your theater?

We often have guests over for dinner and like to show them our beautiful little dedicated theater. I'd love to have them watch a movie but with dinner and conversation there often isn't time for one, so I end up just demonstrating some of the HD stuff I've recorded on Tivo, plus maybe a few minutes of a spectacular sequence from a DVD or two.


What suggestions do you have for a short but complete presentation that would show off the theater and at the same time be really entertaining? Let's put a limit of one hour on it. I have recordings of the Discovery channel that are beautiful but something dramatic would be better.
