A new documentary executive produced by actor Chris Pratt aims to shine a spotlight on some of the greatest unsung heroes of U.S. military history.

“Fighting Spirit: A Combat Chaplain’s Journey” chronicles the selfless sacrifice and service of military chaplains who have ministered to U.S. troops in combat zones around the world.

The documentary, written and co-directed by award-winning filmmaker Rich Hull, debuts in select theaters on Nov. 8 ahead of Veterans Day. The film marks the first-ever collaboration between Hollywood and the U.

S. Army Chaplain Corps. Speaking to The Epoch Times about his latest project from Paulist Productions, Hull said he set out to tell the untold stories of the 419 Army chaplains who have died in the line of duty since the Revolutionary War.

“As I learned more about combat chaplains as a profession, which is really more of a ‘calling,’ and the incredible work they do to serve the soldiers who are on the frontlines serving us as Americans, I was struck by the fact that combat chaplains never like to be part of the story, and so most of their tales have remained undiscovered. Until now,” Hull said. Touching on the film’s title, Hull said he was intentionally vague about which chaplain the documentary is centered on.

“It’s really about a lot of journeys,” he said. Hull said the most compelling narrative presented in “Fighting Spirit” revolves around the life-changing, cross-country journey of former Army combat chaplain Jus.
