The Film They Tried to Bury: Bob Lazar's S-4 UFO Documentary Is Out Now

Bob Lazar has spent decades staying mostly silent about his experiences at S-4. When director Luigi Vendittelli first approached him in December 2021, Lazar did not jump at the chance to revisit the story that changed his life in 1989. Instead, he looked the filmmaker straight in the eye and delivered a serious warning: “You seem like a nice guy. Do you really want to do this? Because you’re probably going to get some problems. You don’t need this in your life.”

Lazar knew the risks better than anyone. Yet after careful consideration, he decided to move forward and give Vendittelli full access. What followed was a multi-year journey of deep collaboration that turned into one of the most detailed documentaries ever made about his claims.

From the beginning, Lazar opened his world to the crew. Over the next several years they filmed extensively at real Nevada locations tied to his story. Lazar personally guided the team through the desert terrain, sharing precise memories of the S-4 facility where he says he worked on nine extraterrestrial craft in late 1988. The production team built full-scale recreations of the hangars and interior workspaces based directly on his descriptions, down to the layout of the propulsion labs and the nine flying discs he claimed were stored there.

One of the most striking moments captured on camera was Lazar getting behind the wheel of a Back to the Future DeLorean in the same Nevada desert where his story began. The scene was not just for show. It served as a narrative bridge, connecting his experiences from the 1980s to the present day in a way that made the decades-old events feel immediate.

Throughout the entire process Lazar remained hands-on. He reviewed details, sat for extensive interviews, and even provided material he had never released publicly in the 35-plus years since he first went on the record. That includes a key photograph taken at the Nevada Test Site that has never been seen before, along with additional evidence supporting his account of reverse-engineering non-human propulsion systems.

The road to today’s launch was anything but smooth. After principal filming wrapped, the project faced nearly a full year of deliberate delays. Two separate parties in the film industry applied heavy pressure on the filmmakers, attempting to force them to sign over exclusive distribution rights. The clear goal, according to the director, was to bury the documentary permanently so it would never reach the public.

Vendittelli also began receiving untraceable threatening phone calls and messages. Lazar’s original warning had proven accurate. Yet both men refused to back down. The film stayed independent, the team pushed through every obstacle, and the final cut preserved every piece of new material Lazar had entrusted to them.

Now, on April 3, 2026, the documentary is finally available for the world to see, featured on Amazon. Lazar’s 1989 claims, once dismissed outright, land at a moment when congressional hearings have featured military whistleblowers testifying under oath about recovered non-human craft and advanced unknown technology. Many in the UFO community have long connected his S-4 story to the 1947 Roswell incident, the event widely viewed as the origin of modern allegations that the government recovered and studied extraterrestrial vehicles.

What did they not want people to see? What is in that never before released photograph? And why did multiple parties work so hard to keep this documentary off Amazon’s platform?
