This sites been up for a long time it seems but it was new to me, the Internet Movie Firearms Database.
The navigation isn't great, but search works good if you know the name of the movie you want to look up the firearms from.
I stumbled across the site looking for the sniper rifle scene in Riddick.
Turns out to be a trusty Savage 110
Anyway, just sharing for some fun. I'm sure some of you other guys have a gawk over movie firearms now and then
