The eagerly anticipated release of Rob Reiner’s final cinematic venture has been put on indefinite hold following the untimely and tragic passing of the acclaimed director.

Titled “Spinal Tap at Stonehenge: The Final Finale,” this film was set to be a grand concert sequel to this year’s “Spinal Tap 2: The End Continues.” Fans were looking forward to seeing it in IMAX theaters in 2026, courtesy of Bleecker Street’s distribution.

However, in the wake of the shocking murders of Reiner and his wife Michele, plans for the film’s release have been suspended. Sources revealed to Variety on Tuesday that the decision was made to pause until a clear way forward is determined in consultation with Rob’s loved ones and family.

Efforts to reach Bleecker Street for their comments have been made by Page Six, though a response remains pending.

The film promises to bring back the iconic trio of Christopher Guest, Michael McKean, and Harry Shearer who will once again step into the shoes of the fictional heavy metal band, Spinal Tap, a role that has delighted audiences for decades.

The movie includes live concert footage filmed at Stonehenge in October. Shania Twain, Eric Clapton and Josh Groban make guest appearances, according to Variety.

A 21-second teaser trailer for the project was released on Oct. 23. It stated that the movie would come out next year in theaters and in IMAX.

“Rock legends Spinal Tap perform at ancient Stonehenge, merging musical and historical grandeur in an amplified finale that perfectly unites the mystique of both the band and the prehistoric monument,” IMDb’s description of the film reads.

1984’s “This Is Spinal Tap” was Reiner’s feature directorial debut. The sequel, “Spinal Tap II: The End Continues,” was released on September 12.

“To me, [Spinal Tap: The End Continues] is more of a, ‘Let’s see where they are now’ than it is a sequel,” Reiner told People in September. “I mean, listen, what kind of sequel do you have 41 years after the first? ‘Oh, we’re trading on it.’ It’s not that, like I said, it’s got to be a standalone.”

Three months before his death, Reiner teased a project that he was working on for over 50 years.

“I’m not going to mention one because it has to be kept under wraps, but I’m going to be shooting something in August,” he told Seth Rogen during an Interview Magazine chat in September.

“I had this idea I’ve had for over 50 years, and I’ve tried a number of times with different writers with different scripts. I’ve never been able to get a good one. I’m going to try one more time and see if I can pull it off. But again, I’ve got to find my way in.”

Later in that interview, Rogen, 43, offered to give Reiner a part on Season 2 of his Apple TV+ comedy “The Studio.”

“I would do it, for sure,” Reiner replied.

The 78-year-old director and his 70-year-old wife were found dead inside their Brentwood, California home on Sunday.

Their son Nick Reiner has been arrested and charged with stabbing his parents to death.

The 32-year-old, who has a history of addiction and homelessness, allegedly got into an uncomfortable yelling match with the couple at Conan O’Brien’s Christmas Party the night before the murders.

Nick is being held without bail.
