Fringe executive producers Monica Breen and Alison Schapker have come aboard to rewrite a mysterious J.J. Abrams project known as Zanbato.

J.J. Abrams' Bad Robot production company has the project set up at Paramount, which is said to deal with, "swashbuckling robots with swords," according to an insider. Zanbato will also delve into aspects of Japanese history and robotics.

Zanbato is just one of many feature projects in development at Bad Robot. There is the Untitled J.J. Abrams Diamond Heist Project, which is also set up at Paramount. It isn't clear when production will start on either project as of yet.

Fringe was recently renewed for a fourth season on Fox, where J.J. Abrams also serves as an executive producer alongside Monica Breen and Alison Schapker.
