Paul McCartney and Elton John star in Spinal Tap 2 trailer 40 years on

The improvised rock mockumentary This Is Spinal Tap hit cinemas back in 1984 and has since become a cult comedy classic.

Now Christopher Guest, Michael McKean, Harry Shearer and Rob Reiner are back over 40 years on for a sequel about the fictional British heavy metal band.

The film's official synopsis reads: "SPINAL TAP is back! After a 15-year hiatus, David St Hubbins, Nigel Tufnel, and Derek Smalls are drawn back together for one last concert. Documentary filmmaker Marty DiBergi returns to explore what the band members have been up to and immortalize the concert reunion. The film blends the same musical mayhem and satire that made the original a cult classic and features some fantastic rock cameos in the process. Will this concert be their triumphant return, or just another Stonehenge-sized catastrophe?"

Joining Spinal Tap this time around are Sir Paul McCartney and Sir Elton John playing themselves. According to the filmmakers, the music legends were naturals at improvisational comedy, having had decades of being asked questions in interviews.

Spinal Tap II: The End Continues hits UK cinemas on September 12, 2025.
