Rob Reiner and Christopher Guest Reunite in Hilarious Spinal Tap II: The End Continues Trailer

Spinal Tap is back!

On Thursday, July 24, Bleecker Street debuted the trailer for Spinal Tap II: The End Continues — the sequel to the groundbreaking 1984 mockumentary This Is Spinal Tap at Hall H for San Diego Comic-Con attendees. Rob Reiner, who directed the original movie and costarred as the fictional documentarian Martin Di Bergi, returns for the sequel, alongside original This Is Spinal Tap band members David St. Hubbins (Michael McKean), Nigel Tufnel (Christopher Guest) and Derek Smalls (Harry Shearer).

The trailer revisits classic moments from the original movie and finds the surviving Spinal Tap members in different places at the time of their reunion. Hubbins appears to play in a mariachi band, Smalls does commercials for cryptocurrency and Tufnel performs with a folk band in a pub. As the group reunites for their first concert in years in New Orleans, they grapple with several new gags and try to convince Questlove to perform as their drummer.

Assuring fans at Comic-Con’s Hall H that the new film is “a lot of fun,” Reiner teased its premise. Spinal Tap, he said, hasn’t played in decades and “nobody talks about them. Then we have a special guest appearance by a big music star, I’m not going to say who. And he’s screwing around in a soundcheck and he starts to sing ‘Big Bottom’ and somebody catches it on an iPhone, throws it up on TikTok, it goes viral. And all of a sudden they’re back in the world.”

“41 years after the release of the groundbreaking mockumentary This Is Spinal Tap, the now estranged bandmates David St. Hubbins, Nigel Tufnel, and Derek Smalls are forced to reunite for one final concert,” reads an official synopsis for the movie. “Spinal Tap II: The End Continues also marks the resurrection of documentarian Marty Di Bergi, who once again tries to capture his favorite metal gods as they contemplate mortality—and the hope that their 12th drummer doesn’t join them in The Great Beyond.”

“Joined by music royalty Paul McCartney and Elton John, Spinal Tap wrestles with their checkered past to put on a concert that they hope will solidify their place in the pantheon of rock ’n’ roll,” the synopsis adds.

Deadline first reported that Reiner, 78, was launching a sequel to This Is Spinal Tap back in May 2022.

“For so many years, we said, ‘Nah.’ It wasn’t until we came up with the right idea how to do this,” he said at the time. “You don’t want to just do it to do it. You want to honor the first one and push it a little further with the story.”

The sequel will include star-studded cameos from music legends, including Garth Brooks and Trisha Yearwood. Paul Shaffer and Fran Drescher, who appeared in the original mockumentary as a promoter and the band’s publicist Bobbi Flekman, respectively, will also reprise their roles in the new film.

Ahead of the sequel’s release, the original rockumentary returned to theaters over the July 4th weekend to celebrate its 41st anniversary. When Reiner spoke with PEOPLE recently, he reflected on how the original movie grew into a cult classic over the decades.

“It’s taken a while, but you never know when you’re going to start shooting something if it’s going to take,” Reiner said. “And this certainly didn’t take right away!”

Spinal Tap II: The End Continues arrives in theaters Sept. 12.
