The high-profile pilot is slated to film late this yea, reported Deadline.
Co-created by Robert Kirkman, on whose graphic novel 'The Walking Dead' was based, and Dave Erickson ('Marco Polo'), the spin-off takes place during the same zombie apocalypse depicted on 'The Walking Dead' but in a different location.
Executive producing the companion series are Erickson, who serves as showrunner, and TWD exec producers Kirkman, Gale Anne Hurd and David Alpert. AMC Studios is producing.
