A forgotten chapter of the First World War is coming back into focus with The War Below, a gripping historical war drama that follows a group of civilian tunnelers entrusted with an extraordinary mission beneath the battlefield. Well Go USA has unveiled the official trailer for the film, offering audiences a glimpse of the dangerous operation that could change the course of the war. Directed by J.P. Watts, the movie revisits the desperate efforts to break the deadly stalemate on the Western Front through underground warfare. Originally released in 2021 in some territories, the film is now set for a wider video-on-demand release, arriving on November 10, 2026. With its tense atmosphere, historical setting and focus on unlikely heroes, The War Below looks set to appeal to viewers who enjoy realistic military dramas and untold stories from history.
Set during World War I, the film unfolds in the aftermath of the devastating Battle of the Somme, when Allied forces were searching for a way to overcome the heavily fortified German positions. The story follows a group of civilian miners known as the “Clay Kickers”, who are recruited to dig tunnels beneath No Man’s Land and plant a massive explosive beneath enemy trenches. Their dangerous assignment forms part of an audacious strategy associated with the Battle of Messines, where underground mines played a significant role in the Allied offensive. Working beneath the battlefield, far from the familiar images of soldiers charging across open ground, these men face suffocating conditions, constant danger and the pressure of a mission on which countless lives could depend.
The newly released trailer hints at the enormous risks involved in the operation. One particularly striking line, “Without us, those tunnels are going to fail,” captures the tunnelers’ determination and the importance of their work. Their mission is complicated by a four-week deadline, hostile military leadership and the constant threat of discovery by enemy forces. Unlike conventional war films that focus primarily on soldiers and battlefield confrontations, The War Below shifts attention to the specialists whose work takes place underground. Every movement must be carefully planned, and a single mistake could put the entire operation in jeopardy. The combination of claustrophobic tunnels, military pressure and the ticking clock gives the film a natural source of suspense, while its historical backdrop adds weight to the characters’ decisions.
The film features an ensemble cast led by Sam Hazeldine, alongside Tom Goodman-Hill, Kris Hitchen, Andrew Scarborough, Anna Maguire, Joseph Steyne, Elliot J. Langridge, Sam Clemmett, Sonny A. Serkis and Douglas Reith. Together, the actors bring to life a story about ordinary men caught up in an extraordinary military undertaking. The premise also offers an opportunity to explore the human side of wartime history, including the fear, camaraderie and sacrifices of workers who were not necessarily trained as conventional frontline soldiers. Their courage is presented not through grand speeches or heroic battlefield charges alone, but through the difficult, dangerous work required to give the Allied forces a chance to advance.
Behind the camera, J.P. Watts makes his feature directorial debut with The War Below. Watts also contributed to the film’s visual effects, helping shape the underground environments and battlefield atmosphere. The screenplay was written by Watts and Thomas Woods, while Luis Guerrero, William Knochel and Chris Lemos served as producers. The film draws on a lesser-known aspect of First World War military strategy: the use of specialist tunnelling teams to undermine enemy positions. By bringing this operation to the screen, the filmmakers offer a different perspective on the conflict and highlight the contribution of people whose efforts could remain hidden even as they helped determine the outcome of major engagements.
With its historical premise, suspenseful mission and focus on overlooked wartime contributors, The War Below offers a distinctive addition to the war-film genre. The trailer suggests a story built around endurance, teamwork and the pressure of making every second count in an unforgiving environment. While the film originally premiered in 2021, its upcoming VOD release will give more viewers an opportunity to discover this account of underground warfare. For audiences interested in World War I history, military strategy and stories of courage beyond the traditional battlefield, the film could be worth adding to their watchlists. The War Below arrives on video on demand on November 10, 2026.
