DVD extras concerning audio...

Hello all, I was watching the Lord of the Rings DVD extras and absolutely love the detail they go into concerning audio for picture, foley, SFX, music composition, etc. Does anyone know of other DVD's with extra features similar to this? I tried a Google search on the topic, but with no avail. The more the merrier! Thanks cloughri

I remember seeing something in Star Wars attack of the clones, also may be the Gladiator.

It doesn't go GREATLY into detail, but shows some really cool things. Check out the Monsters Inc DVD, it has some really cool stuff with interviews and behind the scenes stuff. One of my favorite parts of it is that there's a special audio track on the DVD with sound design only. Really interesting to watch and listen to.
