Fox is developing a movie based on the “Mouse Guard” graphic novel series with “Rogue One: A Star Wars Story” writer Gary Whitta on board to pen the adaptation, Variety reports.

Matt Reeves, director of “War for the Planet of the Apes” is producing “Mouse Guard” through his 6th and Idaho production company along with Ross Richie and Stephen Christy, both of Boom! Stuidos — the publisher of “Mouse Guard.”

Fox is planning a live-action movie through performance capture technology employed in the “Planet of the Apes” films. Reeves directed 2014’s “Dawn of the Planet of the Apes” in addition to the upcoming “War for the Planet of the Apes,” which opens in July, 2017.

David Peterson created, wrote and illustrated the “Mouse Guard” series, set in a medieval times world without humans. The stories center on a brotherhood of mice sworn to serve their fellow mice.

The series was first published in 2006 by Boom’s Archaia Studios Press and has sold nearly a million copies.

Adam Kassan will executive produce for 6th and Idaho. Boom!’s Adam Yoelin and David Petersen will co-produce.

Boom! has tapped James Badge Dale to star in its movie adaptation of “The Empty Man.”
