Woah.. undead thread rises again!
That said.. awesome comedy and i laughed my ass off! Prior to seeing it i read somewhere that Tom Cruise would be in it in some supporting role but when he appeared i didn't recognize him at first.. all i got was a familiar feeling that i saw this guy before.
Then he launched into his Les Grosmann role and i keeled over with laughter and when it actually hit me that it was Cruise i nearly died because it was such an atypical role for him but he played it brilliantly.
2nd nod would be to RDJ.. awesome "brother" he played complete will all the black and especially Vietnam War era clichees out there.
Definitely a must see.. one hilarious movie.
