LOTR: Return of the King (ex), 2003

Body Count: 836
This is a pretty good movie if you are into fantasy and magic. It is not recommended for young viewers for obvious reasons.
300, 2007

Body Count: 600
This movie screams gore. If you have not seen it you should, as it is very cool nonetheless.
LotR: Two Towers (ex), 2002

Body Count: 468
Good, once again, if you are into the series.
Grindhouse: Double Feature, 2007

Body Count: 310
I have not seen this movie, but from the reviews I have read it is really gory.
Hard Boiled, 1992

Body Count: 307
If you like kung-fu action movies with a lot of fighting, this is sure to have the right amount of death and violence for you.
We Were Soldiers, 2002

Body Count: 305
I have not seen this movie and I couldn't find any good reviews, but the title pretty much says it all.
Saving Private Ryan, 1998

Body Count: 255
This is a really good war movie and it has a couple of heart-warming moments, but a lot of really good fighting scenes too.
Equilibrium, 2002

Body Count: 236
This movie is about a utopian society gone wrong, and is a really good and suspenseful movie. If you like movies like the Italian Job, then you're sure to appreciate this one.
Bullet in the Head, 1990

Body Count: 214
Another movie I have not seen but the reviews I have read confirm that it is comparable to other war movies.
A Better Tomorrow II, 1987

Body Count: 199
This is the sequel to a movie I have not seen, so I wouldn't know much too much about this one. Still, the body count is pretty high.
