After nearly 40 years, the Spinal Tap boys are ready to mock ‘n’ roll again.

A sequel to the 1984 rock mockumentary This is Spinal Tap is in production, its release on March 19th, 2024 timed to coincide with the classic film’s upcoming 40th anniversary. Director Rob Reiner and stars Michael McKean, Christopher Guest and Harry Shearer will all be returning.

McKean starred as David St. Hubbins, Guest as Nigel Tufnel, and Shearer was Derek Smalls. Reiner also starred as superfan/movie director Marty DiBergi, a role he’ll reprise in this sequel.

The first film was in the style of Martin Scorsese’s The Last Waltz, the legendary concert documentary that followed the farewell tour of the Canadian-American rock group The Band. The sequel will pit Spinal Tap against DiBergi as he tries to redeem himself and the band after his first movie showed the band in such a bad light.

Spinal Tap 2 will also feature real-life musicians in the film. No names have been revealed yet, but it will likely depend on the artists’ touring schedules.

The spoof, one of the first so-called “mockumentaries,” was released to critical acclaim in 1984. In 2002, it was deemed “culturally, historically, and aesthetically significant” by the Library of Congress, and was selected for preservation by the National Film Registry.

Guest, McKean, Reiner, and Shearer will conceive the new film. Frank Marshall will produce and Matthew George, Jonathan Fuhrman and Hernan Narea will executive produce on behalf of Castle Rock Pictures.

According to Deadline, Reiner said, “the plan is to do a sequel that comes out on the 40th anniversary of the original film and I can tell you hardly a day goes by without someone saying, why don’t you do another one? For so many years, we said, ‘nah.’ It wasn’t until we came up with the right idea how to do this. 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 three members, who wrote the music and lyrics — some with Reiner — for deliberately provocative titles like Smell the Glove, Hell Hole, Big Bottom and Lick My Love Pump, have in the past toured as the band, though not recently.
