Scottsdale, September 8 — A new documentary film, “The Cosmic Trigger,” is set to run Sept. 11–17 at the Harkins Shea 14 Theater, located at 7354 E. Shea Blvd., marking filmmaker Larry L. Sheffield’s third partnership with the theater.
The film, directed by Sheffield and Trent J. Di Giulio, explores the surge of unexplained aerial phenomena over New Mexico immediately following the 1945 Trinity atomic test.
The documentary draws on a range of sources, including never-before-seen footage, documents from historic archives, declassified military records, expert analysis, and historical accounts. This fact-based approach takes a closer look at the question of whether the dawn of the nuclear age acted as a “cosmic wake-up call” to observers beyond Earth. The film’s subject matter is rooted in declassified military records and post-atomic-era surveillance history.
The Trinity Test and Its Significance
The Trinity test, conducted in July 1945 in New Mexico, was the first detonation of a nuclear weapon, part of the Manhattan Project. This pivotal event in the history of the US military has been the subject of much speculation and debate, particularly with regards to the unexplained aerial phenomena that followed. The film’s focus on declassified military records and historical accounts aligns with ongoing public interest in aerial phenomena and government transparency.
The film’s use of declassified military records and expert analysis provides a unique insight into the surge of unexplained aerial phenomena that followed the test.
A Local Venue for a National Conversation
The run of “The Cosmic Trigger” at the Harkins Shea 14 Theater in Scottsdale provides a local venue for audiences to engage with the film and its subject matter.
The documentary continues Sheffield’s documented pattern of producing documentaries about the atomic history of the American Southwest, following his 2024 runs of “Oppenheimer After Trinity” and “The Atomic Rocketeer.” As the film prepares to run at the Harkins Shea 14 Theater, it is clear that “The Cosmic Trigger” will be a significant addition to the conversation about the atomic history of the American Southwest.
With its fact-based approach, the film is set to provide a unique insight into the events that followed the Trinity test, and its implications for our understanding of the world today.
What to Watch Next
As “The Cosmic Trigger” prepares to run at the Harkins Shea 14 Theater, audiences will be watching with interest to see how the film contributes to the ongoing conversation about aerial phenomena and government transparency. With its release, the film is likely to spark a range of discussions and debates about the implications of the Trinity test and its aftermath, and what this means for our understanding of the world today.
