Well you got Ben Stiller, Robert Downey Jr., and Jack Black. There are two others --- typical nerd dude and the black guy.
hahaha loved it!! "thats not real blood!!! thats just red cornsyrup....red cornsyrup that taste like blood"!
I want to see that movie! I heard Tom Cruise was in it, but he was covered heavily on make up so you have to look a bit closer.
