Spinal Tap, the fictional British rock band created by American improvisers and immortalised in Rob Reiner's 1984 mockumentary, return to cinemas this month in Spinal Tap II: The End Continues, reuniting the trio for a contractual "one last gig" in New Orleans and a perilous hunt for a drummer.

In the film, Reiner reprises his role as documentary filmmaker Marty DiBergi and traces what the rockers have been doing in the 15 years since their split. The reunion is triggered after a country cover of the band's song Big Bottom, recorded by Garth Brooks and Trisha Yearwood, goes viral and propels the track back into the charts. That revival activates a previously overlooked contractual clause obliging the group to perform a final concert.

The film follows the familiar comic conceit that the band's backstage and onstage lives are a catalogue of disasters. Frontman David St Hubbins, played by Michael McKean, bassist Derek Smalls, played by Harry Shearer, and guitarist Nigel Tufnel, played by Christopher Guest, are found in unexpectedly prosaic occupations: St Hubbins writes answering machine jingles in Los Angeles, Smalls runs a glue museum in London, and Tufnel sells cheese in Berwick-upon-Tweed.

The script turns the band's notorious record on drummers — a running gag in the original film in which successive drummers meet bizarre ends — into a plot engine. The production approached several high-profile drummers, with Questlove, Metallica's Lars Ulrich and Red Hot Chili Peppers' Chad Smith all declining, according to the actors speaking in character. The role is ultimately taken by a newcomer, Didi Crockett, played by Valerie Franco.

Spinal Tap straddles a curious space between fiction and reality: although the band began as a parody, the group has performed live at real venues including Wembley Arena, Glastonbury, the Royal Albert Hall and Carnegie Hall. That crossover has helped sustain the film's reputation, which grew from a modest box-office showing to a cult classic shared across formats and generations. The sequel includes several celebrity moments designed to underline that blur. Sir Paul McCartney and Sir Elton John appear in the film; McCartney pops into a studio scene while Elton John joins the band on a live rendition of their Stonehenge routine. New material written for the project includes tracks such as Rockin' in the Urn and The Devil's Not Just Getting Old.

The production also nods to the original film's cultural imprint. The band famously insisted their amplifiers "go to 11," a joke that entered broader usage and was even noted in an Oxford University Press phrasebook. In the sequel, Tufnel describes a custom amplifier "that goes to infinity on the dial," reiterating the joke while updating it for a new era.

The characters' creators have continued to fight for control of their invention offscreen. In 2020 the Spinal Tap performers won a four-year court battle to reclaim rights to the characters and related material, a dispute they said followed alleged "Hollywood accounting" that left them with minimal earnings from the franchise.

Early critical reaction to the sequel has been mixed but leans positive. The Guardian awarded four stars, calling the mockusequel "still funny" and noting its "pin-sharp laughs and melancholy." The Radio Times said the beloved characters "deserve a better film," while The Telegraph gave the film three stars and advised fans to "dial down your expectations to -11," acknowledging strong moments but concluding the sequel does not match the satirical precision of the original.

The film incorporates familiar comic set pieces that echo real rock-industry anecdotes. The first movie mined backstage mishaps and eccentric rider demands that have, over the years, been echoed by actual touring acts — from Van Halen's reported M&M clause to tales of artists getting lost in cavernous venues — and Reiner has said the filmmakers tried to stay truthful to the absurdities of touring life.

Spinal Tap II: The End Continues opens in cinemas on Friday, Sept. 12, with a soundtrack released alongside the film. The cast includes new supporting roles that engage with the band's legal affairs and promotion, and the narrative culminates in the planned New Orleans performance that serves as both the plot's contractual fulcrum and its comic climax.

For fans of the original, the sequel offers a chance to revisit characters who helped define a strand of deadpan satire that has influenced mock-documentary comedy for decades. For newcomers, it presents a staged but affectionate portrait of rock excesses and the peculiar afterlives of pop-culture creations.
