Came across a great site that is tallying the death counts in as many movies as it can. The appropriately named Movie Body Counts (www.moviebodycounts.com) has a huge number of movies in its database, and obviously has listed the top movie body counts.
They actually list off the top 101 movies, but once you get the top fifteen, the body counts drop off, and aren't anywhere near as impressive as the top movies. It's not surprising that war movies feature highly in the list, and in particular sword and sandals movies, especially those produced post-CGI age, when vast numbers of virtual soldiers are easily able to be slaughtered on screen. It's not a spoiler to say that the Lord Of The Rings movies feature prominently, with their over-the-top epic battle scenes.
So here goes, in descending order, the current top ten movies with the highest death count.
#9 Titanic (1997): Body Count 307
#8 Hard Boiled (1992): Body Count 307
#7 Grindhouse: Double Feature (2007): Body Count 310
#6 Lord Of The Rings: Two Towers (2002): Body Count 468
#5 The Last Samurai (2003): Body Count 558
#4 Troy (2004): Body Count 572
#3 300 (2007): Body Count 600
#2 Kingdom Of Heaven (2005): Body Count 610
#1 Lord Of The Rings: Return Of The King (2003): Body Count 836
