National Geographic Channel has greenlit The Long Road Home scripted miniseries, based on Martha Raddatz’s New York Times bestseller. It was announced today ahead of Nat Geo’s session at TCA.

The eight-hour event series is executive produced by Mike Medavoy, Jason Clark, Benjamin Anderson and Edward McGurn. The 33 screenwriter Mikko Alanne is penning the adaptation and also executive producing. Production will begin in early 2017 for a premiere later in the year.

First announced as a development project in November, The Long Road Home will relive a heroic fight for survival during the Iraq War when the First Cavalry Division from Fort Hood, Texas, was ferociously ambushed on April 4, 2004, in Sadr City, Baghdad — a day that came to be known in military annals as “Black Sunday.”

The event series will cut between the soldiers on the ground and the homefront in Texas, where their wives and families await news for 48 hellish hours, expecting the worst. The incident, which took place 11 months after President George W. Bush’s “Mission Accomplished” speech, changed the American military’s view of Iraq from a peacekeeping mission to a fight against domestic insurgents.

“With The Long Road Home, we’re going to tell the inspiring story of the selfless heroism and bravery of U.S. soldiers in extraordinary and terrifying circumstances. We’re also going to shine a light on the sisterhood formed by their wives on the homefront as they rally around each other awaiting news of their husbands’ fates,” said National Geographic Channel executive vice president and head of global scripted programming and development Carolyn Bernstein. “We are so pleased to partner with Mike Medavoy, a producer with a remarkable list of credits, including some of cinema’s most iconic military dramas, along with Jason Clark, president of Seth MacFarlane’s Fuzzy Door Productions, and Mikko Alanne to bring the universal and timeless story of these courageous warriors and their equally courageous wives to Nat Geo.”

Alanne is repped by CAA and Media Talent Group. Mike Medavoy, Benjamin Anderson and Edward McGurn are with Gang Tyre Ramer Brown. Jason Clark is repped by Jackoway Tyerman Wertheimer Austen Mandelbaum Morris & Klein.
