I really like some of those movies, but they are drastically overused as demo pieces (I've used half of them, too! 

 ).  Phantom Menace & The Fifth Element are particularly overused.
The most overused discs in my demo library used to be Blade and Spawn, in a dead heat.  Coming in at #2 was Saving Private Ryan.  These have now been permanently retired as demo discs! 
 For a bass extravaganza demo, you might try "Titan AE", especially the ice field scene.  Wow!  This also has the advantage of being a movie that sorta flew under the radar (okay, it was a bomb commercially), so probably not everyone's sick of it yet.
