Pirates 4 Update October 9, 2009 Pirates 4 inspired by Tim Powers’s fantasy novel The fourth Pirates Of The Caribbean movie will reportedly be based on Tim Powers’s 1988 fantasy novel On Stranger Tides. According to the LA Times, Disney has optioned Powers’s book with plans to take elements from his story for its next Pirates instalment: “I’ve watched all the [Pirates] movies several times and I think the clear thing they would use is the trip to the Fountain of Youth,” said Powers. “My main character doesn’t overlap with Jack Sparrow at all. “I suppose they might overlap the Geoffrey Rush character Barbossa and Blackbeard. The only thing I feel certain they will hold on to is the Fountain of Youth since they telegraphed that at the end of the last movie.” Screenwriter Terry Rossio has confirmed that the filmmakers will “draw material and expertise” from Powers’s work.
