Dude

So, Yahoo has the new Pirates of the Carribean trailer.

And there's Davey Jones, who has tentacles all over his face. And something big, with tentacles, which is probably an octopus or a kraken. There's some pics of Davey Jone's ship, and concept art of him in the comments thread here over on eric_m's LJ.

Linguistics

Is there a good word in English for "People who continue to believe something despite copious proof of it being false"?

(And to get the snark out of the way, I'm not looking for Republicans, religious (there's a difference between lack of proof and disproof, and that's REALLY not a can of worms I feel like opening at the moment), idiots, or similar terms. Even though the event that sparked the question is the Republicans who continue to insist Bush is a "straight shooter", in the face of the constant stream of proven lies, falsehoods, and exaggerations from the White House. I'm looking for something a little less inflammatory.)
