Best movies to take advantage of surround sound

Old thread is old... ;)

Some of the recent "motorsports" based movies have great surround:

Turbo (animated)
"Pearl Harbor" - as crappy as that movie was - was awesome in 7.1.
So I was watching Willow yesterday and realized it has GREAT surround sound (I have a 5.1 system) from the directional effects to the sound of the thunder storm. So I'm asking everyone which movies you've watched that have awesome surround sound effects.

Besides Willow, I thought the 3 LOTR movies had great surround.

Great options listed in this thread.

Also, Terminator 2 special editions were used for a lot of the Dolby/THX setups so that may also be a decent option.
