This nifty cartoon by a group of Italian filmmakers distills H.P. Lovecraft's Antarctic misadventure novella into a 30-minute film. The film's subtitled and the animation's not super-complex, but it zips through the story, and some of the visuals are squirm-inducing.
In any case, think of it as a consolation prize for Guillermo del Toro's adaptation not getting off the ground. Plus, it's hard to complain about a cartoon Cthulhu-spawn eating a T-Rex. That's like catnip for me.
