Mermaids, Zombie Keith Richards, and Rum: New "Pirates of the Caribbean" trailer has it all!

The trailer for the the fourth Pirates of the Caribbean flick is out. On Stranger Tides has (so far) got all the things a good pirate movie needs: liquor, angry half-naked ladies and Johnny Depp.

It really does feel much more like the first (and far superior) Pirates film. Plus, mermaids. Automatic win.

Here's the official synopsis:

In this action-packed tale of truth, betrayal, youth and demise, Captain Jack Sparrow crosses paths with a woman from his past (Penelope Cruz), and he's not sure if it's love–or if she's a ruthless con artist who's using him to find the fabled Fountain of Youth. When she forces him aboard the Queen Anne's Revenge, the ship of the formidable pirate Blackbeard (Ian McShane), Jack finds himself on an unexpected adventure in which he doesn't know who to fear more: Blackbeard or the woman from his past.

Fingers crossed this action-adventure attempts to keep it much more simple than the last Pirates movie did. In theaters May 20th, 2012.
