“Pirates of the Caribbean: On Stranger Tides” opens in theaters May 20, 2011, in Disney Digital 3D™, with screen story and screenplay by Ted Elliott & Terry Rossio, based on characters created by Ted Elliott & Terry Rossio and Stuart Beattie and Jay Wolpert, and suggested by the novel by Tim Powers.

Suggested by??

Disney bought the novel years ago and decided to use it as a framework for their own characters. Similar thing happened for Die Hard.  I've seen the "suggested by" credit before but can't remember where.
