Alamogordo, NM — The Sheffield family has shared a major gift with AlamogordoTownNews.org to share with Alamogordo New Mexico residents and beyond, the official trailer for award-winning filmmaker Larry L. Sheffield's newest documentary, The Cosmic Trigger, was sent to 2nd Life Media first — before any other outlet in the country. You saw it here first.
The film is set to premiere on May 16, 2026, at 6:00 PM at the Flickinger Center for the Performing Arts in Alamogordo — the very region where the world's first atomic bomb was detonated on July 16, 1945. There is perhaps no more fitting place on Earth for this story to be told.
"This isn't about myths or folklore. It's a rigorous examination of documented events that challenge our understanding of what happened in the skies above America's atomic frontier." — Larry L. Sheffield
About the Film — The Cosmic Trigger
The Cosmic Trigger: Trinity 1945 is a feature-length documentary produced by Sheffield in collaboration with co-director Trent J. Di Giulio. The film asks a provocative question that has haunted military historians and researchers for decades: did the detonation of the world's first atomic bomb signal humanity's presence to something watching from beyond?
The documentary traces the surge of unexplained aerial phenomena reported over southern New Mexico in the years immediately following the Trinity Test. From 1945 to 1957, military personnel, scientists, and engineers stationed at White Sands Proving Ground, Holloman Air Force Base, and Los Alamos National Laboratory logged a wave of anomalous sightings over these sensitive sites. The incidents included the now-famous "Green Fireballs" — brilliant, glowing orbs that streaked through restricted airspace — as well as structured craft spotted near missile ranges, objects that hovered and accelerated in ways no known aircraft could replicate, and unexplained radar blips with no corresponding planes.
Rather than trafficking in conspiracy theory, Sheffield assembles his case through rare declassified military documents, unseen archival footage, fresh witness testimonies, and expert analysis of early U.S. Air Force investigations. The film had its world premiere at the Oppenheimer Festival in Los Alamos in August 2025, and its Alamogordo screening will be one of its most meaningful — given the city's central role in the story itself.

Who is Larry L. Sheffield — An Alamogordo Native and Acclaimed Filmmaker
Larry L. Sheffield is not just a filmmaker with ties to Alamogordo — he is one of its own. A native of the city, Sheffield grew up aware of the atomic history surrounding his hometown, but it was not until he began researching his family's past that the full weight of that history came into focus. His grandfather, it turned out, had worked on the Manhattan Project under a classified security clearance — moving across three project sites in the span of just two years: Oak Ridge, Tennessee; Hanford, Washington; and Los Alamos, New Mexico. His grandfather never spoke of it while alive. Sheffield only learned the truth after his death.
That discovery launched what would become a defining body of work. In 2019, Sheffield began the research that would eventually produce a trilogy of documentaries focused on New Mexico's atomic legacy. His production company, First Light Productions, is based in Phoenix, Arizona, but his heart — and his filmmaking — has always remained in Alamogordo and the Tularosa Basin.
Sheffield's Filmography and Awards
Sheffield's documentary trilogy on New Mexico's atomic history has earned him more than 33 national and international film festival awards. His films are known for their use of rare archival footage, colorized historical photographs, and deeply personal storytelling grounded in rigorous research.
Alamogordo, Center of the World, Trinity 1945 (2021)
Sheffield's debut documentary told the story of why Alamogordo was specifically chosen as the site of the world's first nuclear test. It used rare photographs and colorized footage to bring the city's pivotal moment to life on screen. The film earned an Award of Recognition from the Accolade Global Film Competition, an Award of Recognition at the Best Shorts Competition, and four total festival recognitions. Sheffield's stated hope was to donate the film to the Tularosa Basin Historical Society Museum as a permanent gift to his hometown.
Oppenheimer After Trinity (2023)
The second film in Sheffield's trilogy explored the inner world of J. Robert Oppenheimer before, during, and after the Trinity detonation. It featured rare footage and testimony from Oppenheimer's grandson, Charles Oppenheimer, and sold out every scheduled screening in Los Alamos. It won Best Historical Film at the Cannes World Film Festival, Best Documentary Short at Indie Short Fest in Los Angeles, a Platinum award for Best Producer at the Independent Short Awards in Los Angeles, and Outstanding Achievement at the Royal Society of Television and Motion Picture in West Bengal, India — earning ten awards in total.
The Atomic Rocketeer (2024)
Sheffield's third major film chronicled the story of Wernher von Braun and Operation Paperclip — how America brought captured German rocket scientists to the New Mexico desert to advance its aerospace ambitions at what is now White Sands Missile Range. It premiered at the Flickinger Center in Alamogordo in May and June of 2024. By that point Sheffield had accumulated 22 film festival awards, with the most recent being Best Historical Film at the Cannes World Film Festival for his Oppenheimer work.
The Cosmic Trigger (2025–2026)
With The Cosmic Trigger, Sheffield steps into new territory — extending his documentary lens from the bomb itself to the strange phenomena that followed in its wake. As the United States grapples with a new era of federal UAP (Unidentified Aerial Phenomena) disclosures, Sheffield's timing could not be more relevant. The film had its world premiere at the Oppenheimer Festival in Los Alamos in August 2025 and comes to Alamogordo on May 16, 2026.
