Peaky Blinders filmed at 'little known gem' Kelmarsh Tunnel The latest installment of the Peaky Blinders series, titled The Immortal Man, has utilized a lesser-known filming location in Northamptonshire—a disused railway tunnel known as Kelmarsh Tunnel. While the show is typically associated with Birmingham, the production team has highlighted the unique charm of this hidden site, which played a significant role in the film’s visuals. Kelmarsh Tunnel, located on the former Northampton to Market Harborough line, is a 480-meter-long unlit structure. Director Tom Harper described the tunnel as a "treasure" discovered during filming, emphasizing its enclosed nature, which allowed the production to shoot without interference from the public. The remote location also meant that few fans of the show could catch a glimpse of the filming process, adding to its mystique. The film follows Oscar winner Cillian Murphy as Tommy Shelby, the gang leader, returning to Birmingham during World War Two. Set in 1940, the story unfolds amid the backdrop of wartime destruction. Harper noted that the tunnel’s inclusion was crucial to the narrative, as it provided a striking and atmospheric setting for key scenes. The production team took advantage of the tunnel’s unique qualities to enhance the film’s visual storytelling. While the series is set in Birmingham, its creator, Stephen Knight, revealed that most of the original filming took place in Manchester, Leeds, and Liverpool. However, for The Immortal Man, Knight emphasized the importance of returning to the "heart" of the story, which led to additional filming in Northamptonshire. The combination of locations, including the tunnel, allowed the production to blend historical authenticity with cinematic flair.#cillian_murphy #peaky_blinders #tom_harper #kelmarsh_tunnel #stephen_knight
