How about a film entitled: Baraca. It was shot in 27 different countries around the world on 70mm film. It's a show piece rather than a movie in that it is scenes from around the world set to music and sound effects. Baraca translated roughly means "essence of life"
The DVD transfer is gorgeous and it has a very good, if not excellent 5.1 soundtrack.
I have a home theater myself, but my passion is 2 channel audio. When I put this film on though, it provides the glue that makes me realize that properly executed, HT can produce the same emotions (at times) that a high quality vinyl playback system is capable of.
