While plot details are being kept in Davey Jones’ locker, the project, in early development, is not intended to be a spinoff of the long-running franchise that had pirate Jack Sparrow at its center, but rather a wholly original story with new characters under the Pirates moniker, itself inspired by the long-running attraction at Disneyland.
The new project is said to be separate from the already announced reboot of the popular franchise that has Pirates scribe Ted Elliott and Chernobyl creator Craig Mazin developing the story.
