“Micro Loup” is a 2003 animated short by Richard McGuire. It’s about a microscopic wolf, with obvious (and hilarious) nods to King Kong, and it’s the best 7 minutes you’ll have all day.
McGuire’s entry in the Peur(s) du Noirs animated horror short anthology film is one of my all-time favorite shorts, so try to find that on DVD. You can also check out a clip from it, which is only the tip of the iceberg of the short’s full awesomeness, on McGuire’s Vimeo page.
