It's Saruman in RotK, when they overtake him on the road away from Gondor. He was mocking them... I think his exact line might've been to Gandalf or Galadriel, and said something of the like "And what ship will then carry you hence? It will be a gray ship, full of ghosts." I'm working by memory though... but I think that was the idea of the scene...
I always loved that line, though, so yes.
