The co-director of Guillermo Del Toro's Pinocchio, Mark Gustafson, will be developing a new animated mystery series Milepost 88. Animation studio ShadowMachine, which was co-founded by Gustafson along with Alex Bulkley and Corey Campodonico, will be developing the new project, and the trio will also serve as the executive producers of the series. ShadowMachine also worked behind Pinnochio.

According to Deadline, Milepost 88 is based on an original idea from  Mark Gustafson. The series tells the story of two brothers who run a gas station, and their life turns upside down after a stranger unlocks a mystery involving their family history.
