Three words: ZOMBIE VERSUS SHARK.

Mad props to Derek, who works in the office of my department, for alerting me to the existence of the Italian film Zombie, which features (according to Derek) the only cinematic staging of zombie vs. shark to date.

IMDb associates the following "plot keywords" with this film:
Blood / Cannibalism / Cemetery / Eye Skewering / Intestines

And, let us not forget, a zombie fights a shark.

We must see this film, and soon.
