This is nice: Screen Caps is a site presenting HD-quality screen captures from movies, without commentary or explanation. Just big crazy screen caps, many of them suitable for desktop wallpaper. Below are a few of my favorites (sized down to fit this blog) -- can you figure out what movies they're from?
Warning: there is a tiny bit of cartoon nudity on the Screen Caps site. In general I'd say it's NSFW if people are totally checking out your business; there's also one live-action screen cap of some bare rears in the distance. No big deal, but just thought I'd warn ya.
