The 11th plague was "Piranha 2: The Spawning"

James Cameron's post-Titanic life is just getting weirder and weirder:

In The Exodus Decoded, a 90-minute documentary that will be shown in America this month, Cameron and Simcha Jacobovici, the Canadian film producer, claim a volcanic eruption on the Greek archipelago of Santorini triggered a chain of natural catastrophes recorded in the Bible as the 10 plagues that God visited upon Egypt as punishment for enslaving the Jews. Cameron believes the parting of the Red Sea may have been a tsunami that destroyed the pharaoh's army as it pursued the escaping Jews. The documentary claims the episode occurred not at the Red Sea but at the smaller Sea of Reeds, a marshy area at the northern end of the Gulf of Suez. An underwater earthquake may have released poisonous gases that turned the waters red. ... If the waters were poisoned, amphibians would hop ashore, producing the biblical plague of frogs. When the frogs died, insects would have bred on their bodies leading to plagues of locusts, fleas and lice. They in turn would have spread disease to humans, the plague of boils, and animals, the plague of dying livestock. They would also have threatened crops, forcing the Egyptians to store grain which might have then turned mouldy. Contaminated food might account for the plague of deaths among first-born Egyptian males. Weather conditions spawned by the eruption might also have caused the plagues of hailstorms and darkness.

With a hat-tip to Cecil B. DeMille, this could make a heck of a blockbuster if Cameron made those kinds of movies anymore. I can see it now, recast a la Titanic as a historical romance: "Nothing on earth could come between them. Except God. And the Sea of Reeds."
