Corbell’s ‘Sleeping Dog’ Documentary Opens in 6 Days and the Cast Includes Bob Lazar, David Grusch, and Files From a Dead Los Alamos Cybersecurity Official.

Jeremy Corbell’s documentary Sleeping Dog releases to US theaters and digital platforms on May 12, 2026 — six days from today. It has been described by its director, Michael Lazovsky, as the culmination of a decades-long investigation into UAPs. Corbell himself calls it “the most difficult thing I have ever allowed people to see, personally.” The film’s cast is among the most significant ever assembled for a UAP documentary: it includes Bob Lazar, whose 1989 claims about reverse-engineering alien craft at a site near Area 51 have never been officially confirmed or debunked; David Grusch, the intelligence community whistleblower who testified before Congress in 2023 that the US government possesses non-human craft; Commander David Fravor, the Nimitz pilot who described the Tic-Tac UAP encounter; and journalist George Knapp. The centerpiece of the film, however, is a set of files from Los Alamos National Laboratory, passed to Corbell by the son of a recently deceased senior cybersecurity official who worked there.

Some background on who is in this film and why each person matters.

Bob Lazar first appeared publicly in 1989 via a Las Vegas television interview arranged by George Knapp, making claims that he had worked at a facility called S-4, adjacent to Area 51, and had been employed to reverse-engineer propulsion systems from what he described as recovered alien spacecraft. His claims were dismissed as fabrication by the US government, which denied his employment records existed. Over the following three decades, investigative work by Knapp and others confirmed several ancillary details of Lazar’s background that he had been told were fabrications — including his employment at Los Alamos, which was confirmed via documents and a Los Alamos National Laboratory phone directory. The core claims remain unverified by any official source. He appeared in Corbell’s 2018 documentary Bob Lazar: Area 51 and Flying Saucers, which became a significant cultural touchstone in the disclosure movement.

David Grusch is a more recent figure. He served as the representative of the National Reconnaissance Office to the Pentagon’s UAP Task Force from 2019 to 2021 and later as co-lead for UAP analysis. In 2023 he testified before the House Oversight Committee, under oath and with congressional immunity protections, that the US government has been in possession of UAP craft of non-human origin and that a secret legacy program manages this material outside of congressional oversight — including keeping presidents out of the loop. The Defense Department denied his core allegations without addressing the specific claims in detail. No charges were brought against Grusch for his testimony.

Commander David Fravor commanded the Nimitz strike group when the encounter now known as the Tic-Tac UAP occurred off the coast of San Diego in November 2004. He has consistently described, in public testimony and interviews, seeing an object with no wings, no exhaust, no visible propulsion, and flight characteristics that he, as a combat pilot with decades of experience, cannot explain. The 90-second video of the encounter — now publicly available — was obtained and released by the Stars Academy, the organization co-founded by Tom DeLonge that first brought Navy UAP footage to public attention in 2017.

The Los Alamos Files

The specific material that makes Sleeping Dog unusual relative to the existing body of UAP documentary work is the Los Alamos cybersecurity files.

According to reporting in The Vetted Show’s preview of the documentary, Corbell came into possession of files belonging to a former senior cybersecurity official at Los Alamos who died. The official’s son, upon his father’s death, recognized the significance and potential danger of the documents left behind and contacted Corbell. The documents reportedly contain government records related to the study and concealment of UAP craft and their origins.

The significance of Los Alamos in this context extends beyond the documents themselves. Los Alamos National Laboratory has been the primary US nuclear weapons design facility since the Manhattan Project. It has appeared repeatedly in the UAP-linked disappearance story that has generated congressional inquiries throughout 2026: Anthony Chavez, a former LANL employee, disappeared in 2025. Melissa Casias, an active LANL administrative employee with security clearance, disappeared in 2025. The pattern of disappearances centered on nuclear and aerospace research personnel has been formally reviewed by the FBI since April 2026, following White House confirmation that a holistic multi-agency review was underway.

Sleeping Dog was directed by Michael Lazovsky and produced in secret. Corbell describes it as documenting the pressures and personal costs of his investigation — “paranoia, threats, and the constant anxiety over whether you might be in too deep.” Lazovsky, who entered the project as an outsider to the UFO community, described his experience making it: “I was shocked. Not only by Jeremy Corbell’s investigative journey — but by the extent to which he has influenced public transparency, and the remarkable level of engagement he receives on a daily basis by intelligence agencies.”

May 12. Six days.
