Any of the recent submarine flicks should work well for surround usage.

U-571
K-19
Below (Don't forget about this one!)

When a submarine submerges in "Below", I felt like I needed to hold my breath 'cause I was underwater!

Duh...I forget my favorite surround reference...

The Effects only tracks on either "A Bug's Life" or "Monster's Inc." On both of them, the ambience should really fill up the room.
