Games to play with a Movie Theater setup

My friend and I have organized an Xbox Party at Silvercity (a big movie theater chain in Canada) for a friend's birthday. We have 2 hours to play games on a massive movie theater screen with movie theater sound system. Any one have any suggestions? Looking for games that would just be awesome to see and hear in that setup. We will have 4 controllers, but won't have time to really enjoy and play a good co-op game. We'll make the time for Reach since it's his favorite. We've already brain stormed;
 
Halo: Reach
Split/ Second
Burnout Paradise
Super Street Fighter 4
Mass Effect 2
Gears of War 2
The Orange Box

The Orange Box is probably the weakest on that list for the theater thing.
 
Other than that, you have a pretty good list going!

Call of Duty?

Left 4 Dead 2 sounds perfect.

Dead Space. You seriously will shit your pants

black ops
