The trailer for Pirates of the Caribbean: On Stranger Tides is now online. Loosely based on Tim Powers’ novel One Stranger Tides, the film continues the story of Jack Sparrow and Barbossa…sans Orlando Bloom and Keira Knightly. Oh, and Blackbeard (played by Ian McShane) will be in it as well.

Interestingly, On Stranger Tides was part of the inspiration for the brilliantly hilarious Monkey Island series of video games (along with the original Pirates of the Caribbean ride). Similarly, the Pirates of the Caribbean movies seem to have borrowed a gag or two from the Monkey Island games.

Pirates of the Caribbean: On Stranger Tides will be released in theaters on May 20, 2011.
