What do you get when you combine pop culture, gun nuts, and wiki software? The Internet Movie Firearm Database. The site is one of those insanely detailed resources, in the vein of Poobala's Crossovers and Spinoffs Master Page, that the Internet was made for. Most of the entries in the IMFDB give a rundown of all weaponry in the movie or TV show along with some trivia and behind the scenes info. For instance, who knew that the minigun in Predator and Terminator 2 were the same prop?
A fun site, a nice time waster, and a good companion for my upcoming holiday viewing of Die Hard.
