Good 5.1 Demo Material

[allstar780]

Alright so at my work we're having a "Sound-off" demo contest, and the basic premise is... it can be music or a movie, or one of each (you will be judged on the one everyone likes best) and the prize is apparently some money or something lol... but the room the Sound-off will be taking place in is of course our sound room,

I have a lot of options for surround setups (probably going with the Klipsch RF-82 package run off the Onkyo 875)
The TV in the room is the Panasonic 42PZ800U and it is running on the Sony BDP-S300

I currently have Hotel California (hopefully on DVD if i can find it) as my opener demo (it's a great song for speaker demos with awesome bass) but I am looking for something to really show off the surround sound. Anybody got any suggestions? I'm thinking I Am Legend (the scene where the creatures find out where he lives and he has to blow up the cars and shoot the one)

But I do need this by next thursday (the 12th) so any help is appreciated!
