I've created stand-alone clips for demos in my home theater. Instead of switching discs and skipping chapters, I've created/edited video files that are stored on my media server and played-back using a Home Theater Personal Computer.
I think the ideal demo scene is comprised of the following:
- lots of action
- some setup before the action so viewer isn't lost or thrown-into the action too abruptly
- some humor
- and of course, great audio and video
Here are some of my favorite demo scenes. Most are edited clips taken from my Blu-ray disc backups, but some are (still) standard-def versions from DVD backups.
Serenity: Firefly takes on the fleet with help from the Reavers (but stop immediately after Wash says "I am a leaf on the wind. Watch me soar." for the last time.)
Air Force One: The dogfight scene (MiG-29s attack Air Force One, F-15 counter-attack)
Iron Man: Suits up and flies to the desert, frees hostages, blows-up tank, attacked by F22s
Spider-man 2: Abduction of Mary Jane from coffee shop, fight with Doc Oc on the train, stops the train
Superman Returns: Superman saves the crashing plane.
The Matrix: Neo/Trinity gunfight in the lobby, infiltrate building and save Morpheus, helicopter crash.
Kill Bill: The final sword fight between Uma Thurman and Lucy Liu, starting where Uma steps out on to the snow and the music starts playing.
Casino Royal: Opening chase scene.
Quantum of Solace: Opening chase scene.
Transformers: Scorpion fight in the desert; also the opening scene.
The Dark Knight: Joker/armored truck chase scene in the tunnel; also the opening scene.
Star Wars Episode 3: General Kenobi vs. General Grievous (unfortunately, there is a cut to another scene half-way through the fight. I created a demo version and edited the other scene out.)
Star Wars Episode 2: Jedi battle at the Geonosian execution arena; Yoda vs. Dooku light saber fight.
Toy Store 2: The opening sequence of Buzz Lightyear vs. Zurg.
A very good action list, but to get everyone's attention from the start, I would add the deep see explosions of the movie U-571
The launch scene from Contact with Jodie Foster has always been one of my favorites.
