Nope, that was one of the rumored titles before they officially announced the movie, but since then we've known the title to be On Stranger Tides. The plot, however, does revolve around the Fountain of Youth.
I grabbed the background and cropped out the logo, gotta say I do love how they did stick to the Sparrow Skull and Crossbones, though I'm not very fond of the metallic finish this one has. Think I preferred the tried and true skull and golden font to this. Ah well, a Pirates movie is a Pirates movie and through my doubts of them losing Keira and Orlando this doesn't look to disappoint so far.
