The new episodes of the movie Pirates of the Caribbean is promoted online in partnership with Google Earth. Basically they have created a map of a fictional island in the Caribbean, on which users can navigate and discover the movie related content.

I must say I didn't spend much time browsing the island... maybe because I didn't find it very interesting... maybe because it appears to simply be a sort of external (unusual) menu to navigate the movie's content (trailer, downloads etc...).
