There have been some concept pictures leaked onto the Internet on the Pirates of the Caribbean: At World's End film and there are a few spoilers in there for the story progression, as well as an artificially increased Keira Knightley.

I don't hold out a great deal of hope for this having found Dead Man's Chest (Filmstalker review) such a half attempted stop gap at a film, but it was full of exciting set pieces. I'm hoping they recapture the magic for this final film. From all looks of it they have the plot.

You can see the images over at AICN, and they do give some storylines away but nothing major I think. One drawing shows Elizabeth Swann leaning into a table and pouting like mad, and I think the artists have been having a little fun with that drawing!

It certainly looks like the epic with which to end the series doesn't it?
