There's a shitty bootleg trailer out and about now, that you should check out.

Also, here's a concept art picture of the main villain, Davy Jones (played by Shaun's dad from Shaun of the Dead)
Compliments of blairerickson.
There's concept art of the pirates and the ship too, but fuck you guys I'm not gonna save and re-upload all those pics. You only get one; Siamese Pirate Zombie Mutants
The whole crew is mutant zombie pirates. The first movie gave us zombie pirates. The second movie gives us MUTANT zombie pirates. The third movie is supposed to give us NINJA pirates. This is the best movie series ever.
