Pirates of the Caribbean movies heavily borrowed from &quot;On Stranger Tides&quot; from the very first movie, so it was only fair that they eventually actually licensed the book, even if only to mostly just use the (fantastic) title, because they&#x27;d already picked so much of the book apart.<p>Also, further mutual inspiration trivia between the two franchises: Ron&#x27;s never made it a secret that Monkey Island was also directly inspired by the original Disney Pirates of the Caribbean attraction. (The influence of which can be felt strongly throughout, but which most directly manifests itself in the complicated and controversial MI2 ending.)
