Moving cities are no longer a science-fiction marvel. One, in particular, is making its way across the Atlantic for a Nov. 20 U.S. debut.
Remember the decadent fountains, majestic opera house and city-like interior of the gargantuan Fhloston Paradise in "The Fifth Element"? Or the blazing billboards of dozens of shops and cafés and at-your-foot entertainment aboard the Axiom in "WALL-E"? Well, move back a couple of centuries, and you'll find that the amenities of those ships are now available on the world's largest cruise liner, the Oasis of the Seas.
