On the heels of Strike Back and Transporter, Cinemax is developing another action drama series, Sandbox. It centers on a group of Iraq and Afghanistan war veterans who return to the Coachella Valley to discover their hometown has been overrun by criminals. The men decide to use the skills they learned in combat to clean up the town, with unexpected results. Feature writers Andre Fabrizio and Jeremy Passmore (Red Dawn, The World After) will write the script, with Steve Kronish (24, The Kennedys) on board as showrunner. The three, all repped by Paradigm, will executive produce with Larry and Chuck Gordon. Passmore and Fabrizio, who are writing The World After with Len Wiseman set to direct and recently rewrote Hellifield for Lorenzo di Bonaventura, are managed by Aperture Entertainment’s Adam Goldworm.
