Duel of the Kraken Gods

When I first saw the trailer for the upcoming movie Clash of the Titans, I was struck by how much Liam Neeson's Zeus' character command of "Release the Kraken!" echoed Bill Nighy's Davey Jones' character declaiming almost the same or the same words in Pirates of the Caribbean: Dead Man's Chest. Perhaps this is what you call a homage from one film to another. "Release the Kraken!" indeed.
