Movie Body Counts

This site links to a friendly forum for submitting counts and chatting about movies. It also includes some great features such as chart views, search by director and actor and of course a huge collection of movies already submitted.
Bodycounters is for the hardcore kill counter, including counts of every body in given films. From cats and dogs to aliens and engagements the stats are here.
