Brothers Under Fire (Sierra Madre) was a chance to make an action film that was character-based, on themes that questioned immigration, citizenship and the American dream, says director Justin Chadwick.
In the film Captain Jordan Wright (Kiefer Sutherland) and his U.S. Special Infantry squad are granted leave from their mission to watch their gunner-medic Alberto (Tommy Martinez) get married in a small South
American town. Tragedy strikes when Alberto is ruthlessly killed during the celebrations. Heartbroken but resolute, the squad vows to defend the town and avenge their fallen comrade against the cruel Cartel leader, Baker (Omar Chaparro), who has put the town under siege. Rallying the townspeople and utilizing their tactical expertise, they begin to undermine the Cartel’s grip. With Baker’s forces closing in from all sides, Wright’s men defend their own and risk everything in a full scale battle to protect the only family the Captain has left.
Brothers Under Fire occupies a significant place in contemporary war cinema because it reframes the familiar narrative of soldiers in crisis through a lens of moral disorientation, fractured masculinity, and the uneasy entanglement between personal ritual and geopolitical violence, using the chaos of a cartel ambush not as spectacle but as a pressure chamber that exposes the psychological seams of a modern military unit.
The film rejects the triumphalist arc that often defines American war stories and instead traces the slow erosion of command, trust, and identity as a group of soldiers—initially traveling to Mexico for a wedding—are forced into a survival scenario that strips them of structure, hierarchy, and certainty. Its significance lies in how it positions the Sierra Madre region not as a mythic frontier but as a liminal space where national borders, moral codes, and personal histories collapse, leaving only the raw, unmediated instinct to endure.
The film’s tension emerges from this collapse: the soldiers’ training becomes both their salvation and their curse, enabling tactical survival while intensifying the paranoia, aggression, and emotional shutdown that prevent them from functioning as a coherent unit.
In this way, Brothers Under Fire becomes a study of the psychological aftershocks of militarisation, suggesting that the battlefield is not a place but a condition that follows these men wherever they go. Its significance also extends to its portrayal of violence: the film refuses stylisation, presenting conflict as abrupt, disorienting, and morally ambiguous, emphasising the human cost rather than the tactical choreography.
This approach aligns the film with the post‑9/11 lineage of war narratives—works like The Hurt Locker and Lone Survivor—yet it distinguishes itself by situating the violence within a civilian context, forcing the audience to confront the uncomfortable proximity between military intervention and the everyday lives of those caught in its wake.
Thematically, the film interrogates the idea of brotherhood, revealing it not as a sentimental bond but as a fragile, often volatile pact forged under duress, one that can fracture as easily as it forms. Sutherland’s character embodies this tension: a leader whose authority is constantly undermined by circumstance, guilt, and the impossible task of protecting men who no longer believe in the mission, the terrain, or themselves.
Shot in Colombia, the film’s visual language reinforces this instability, using dense forests, shifting light, and claustrophobic compositions to evoke a world where orientation—moral, spatial, emotional—is perpetually slipping.
Brothers Under Fire is significant because it refuses to offer resolution; instead, it leaves the audience with the unsettling recognition that survival does not guarantee meaning, and that the true battlefield is the interior landscape each man must navigate long after the gunfire stops.
The screenplay for was written by Delbert Hancock and Ian Mackenzie Jeffers.
Director’s Statement
As we developed the project, themes of family, friendship and love emerged. Our starting point was a true story of a young South American soldier who was killed just after he’d been given U.S. citizenship, after he’d served three tours in combat. Our low budget was challenging but also gave us an opportunity to tell a story of a group of soldiers dropping into a real community. Their presence in that community leads to devastating consequences. We shot the film in four weeks in a remote, mountainous part of Colombia, using a talented group of first-time filmmakers as heads of departments. Apart from the first-time director of photography and first-time editor from the UK, all the crew were Colombian. Their expertise was invaluable to the way we shot the film. We were keen to set the film in a real environment in a real community using non-actors and local talent. Many of the scenes were improvised. Our Colombian team were keen to help tell a story that deals with the families that are dealing with modern day cartels, and the problems arising out of globalization.

Delbert Hancock is a screenwriter best known for co‑writing the film originally titled Sierra Madre—later released as Brothers Under Fire. Although biographical information about Hancock remains limited in public archives, his credited work positions him within the emerging generation of writers contributing to modern action‑survival cinema. His association with the project places him alongside established genre voices and suggests a creative interest in stories shaped by pressure, violence, and the psychological unraveling of men in extreme environments.
