The film Sand Castle (2017) is not a true story, but it is inspired by real experiences.
The screenplay was written by Chris Roessner, who actually served in Iraq as a machine gunner in the U.S. Armyโs 4th Infantry Division in 2003. The movieโs events โ a unit tasked with repairing a water pumping station in a hostile Iraqi village โ are fictional, but they reflect the kinds of missions U.S. soldiers carried out during the early years of the Iraq War.
So:
Not based on one specific true story or mission.
Draws from the writerโs real deployment experiences, aiming to capture the daily struggles, moral dilemmas, and frustrations of soldiers during the occupation.
๐ Itโs best described as a fictional war drama rooted in reality, rather than a direct historical account.
