The Mummy's Poster Was Banned From the Tube, Not the Film
and Only One of Four Complaints Was Upheld
On 5 August 2026 the Advertising Standards Authority told Warner Bros to stop running an outdoor poster for Lee Cronin's The Mummy. The close-up image on the London Underground and on billboards, it ruled, gave "a realistic impression of a dead child". That was enough to make it unsuitable for any outdoor site where a young child might pass it — even though the same campaign's television and streaming trailers, carrying much the same imagery, were left untouched.
That is the sentence that produced the headlines, and it is worth reading slowly, because most of the coverage compressed it into three words — the film "banned" in the UK — that the ruling does not support. The film was not banned. It played in cinemas in April and was classified 18. What the ASA ruled unsuitable was one still image in one kind of placement, and it did so on one of four separate points it investigated. The other three it dismissed.
One complaint upheld, three thrown out
The campaign came in four pieces, and the watchdog took each one on its own. There was a television trailer, cleared by Clearcast with a restriction that kept it off screens before 7.30pm. There was a version of that same trailer running on Prime Video. And there were the posters: a close-up on the Underground and the identical image on outdoor billboards.
Thirty complaints arrived, many from people who said the advertising had distressed children and adults. The ASA turned those into four questions. Was the TV trailer scheduled carefully enough? Was the Prime Video version targeted away from children? Were the posters fit to stand in a public space where anyone could walk past? And, separately, were the posters offensive or insensitive given how closely the face resembled a dead child, at a time of visible grief in the wider world?
Only the third question was answered against Warner Bros. The trailer's scheduling held. The streaming version's placement held. The offence charge against the poster was rejected outright. What failed, and the only thing that failed, was the poster's suitability for an untargeted outdoor site. "One was Upheld and three were Not upheld," the ruling states in its first line — a split that a headline about a banned film quietly loses.
Why a horror poster read as a dead child
The image is a horror poster doing an ordinary horror-poster job. It shows a female figure in close-up with a mummified appearance, one eye swollen shut, wrapped in brown material that runs up over the head and is inscribed with ancient-looking symbols. Alongside it: "SOME THINGS ARE MEANT TO STAY BURIED," the film's title, and an April cinema date.
The ASA's objection was not that it was gory or violent — it accepted the poster contained no blood, no weapon and no threat. Its objection was narrower and, in a way, more uncomfortable. The grey and ashen skin, the dry and cracked lips, one eye swollen shut and the other "fixed and vacant," the sunken and lifeless set of the face — together, the regulator decided, these read not as a monster but as a corpse. The wrapping "gave the appearance of a shroud." And because the features were recognisably human, viewers were "likely to understand it as a realistic depiction of a dead child."
Warner Bros had built the poster to avoid exactly that reading. The character, it explained, is a living mummy — a young woman returned to her parents years after being taken as a child, not a body. The face carried a neutral expression on purpose; there were no restraints, no sarcophagus, none of the framing that signals death. The studio even argued that the one open blue eye "connoted life, rather than lack of it." It was a careful defence, and it lost, which tells you something about how little control an advertiser has over the meaning of a face once it is enlarged on a wall. The design intent was life; the received impression was death; the regulator went with the impression.
The trailers the watchdog let stand
The two moving-image ads survived, and the reasoning is the more instructive half of the ruling, because it shows where the line actually sits.
The trailer opens on a family taking a phone call: a daughter, Katie, missing for eight years, has been found alive. The father's line — "What was our daughter doing in a 3,000-year-old sarcophagus" — sets the horror turn, and a few images follow: a body lifted from a sarcophagus, a greying hand with long brittle nails brushing a woman's cheek, a close-up of a woman with straggly hair and an eerie smile. The mother's closing line is "I just want my daughter back."
The ASA agreed those moments could unsettle young children. But it found the horror was implied and fleeting rather than sustained, with no gore and no serious violence, and — crucially — that the post-7.30pm scheduling did the protective work the poster's placement could not. Clearcast, which cleared it, reported an average children's viewing index of 31 across all the slots, well below the level that raises concern, with most placements landing near 9pm. The trailer was likely to distress a young child, the regulator accepted; the timetable made it unlikely a young child would be watching.
The Prime Video version turned on the same distinction. Warner Bros pointed to Amazon's targeting toward viewers "in-market" for horror, but the ASA was unimpressed by targeting on its own: streaming accounts, it noted, are commonly shared across a household, so adult-audience targeting "would not necessarily prevent children from seeing an ad." What saved the streaming spot was the same 7.30pm watershed applied to the broadcast version, not the clever targeting.
A poster cannot be scheduled. It is up until someone takes it down, in front of whoever passes — which is precisely why the same image that passed as a timed trailer failed as a static one. This is the practical boundary the ruling draws, and it is a cleaner one than "banned" suggests: not this picture is forbidden, but this picture is fine where you can control who sees it and when, and not fine where you cannot.
The 100-metre rule that stops at the school gate
The most consequential detail is the one that got the least attention, and it is not really about a mummy at all.
Warner Bros had a safeguard for horror advertising: keep the posters at least 100 metres from any school. On this campaign, that rule held. The ads were not near a school. The placement that tipped the ruling was a billboard "visible from a children's nursery" — and the industry's protective buffer does not reach it. The studio's own outdoor-buying instruction is built around a schools list that, as it told the ASA, "did not include nurseries." The media owner Bauer applied a 100-metre exclusion of its own, using the industry-standard SPACE dataset, which covers primary, secondary, special-needs and further-education sites. Nurseries are on none of these lists.
So the buffer designed to protect the youngest children is drawn around a map that leaves out the places the youngest children spend their days. Every party in the chain followed its rules, and the safeguard still had a hole in exactly the shape of a nursery. That gap, more than the artwork, is what decided the case — and unlike a single poster, it will still be there for the next horror campaign unless someone redraws the list.
It is a familiar pattern once you have seen it a few times: a rule that reads as protective right up until you check what it actually enumerates. The same thing runs through how the word "ban" gets used at all.
What "banned" is doing here
Strip the ruling to its remedy and it is narrow. The ASA does not fine; it has no power to. It told Warner Bros that the poster "must not appear in the form complained of," and to keep future distressing marketing away from where young children are likely to see it. On the trailers, "no further action." That is the whole of it — issued, worth noting, nearly four months after the film opened in cinemas in April, by which point the campaign it concerned had largely run its course.
None of that is nothing. A public regulator finding that a major studio's poster read as a dead child is a real result, and the placement gap it exposed is a real problem. But it is a different result from the one the headlines described, and the distance between them is the story. "Banned" is a word that keeps getting stretched over decisions much smaller and more specific than it implies — which is a habit worth watching wherever it appears. When Four Institutions Banned Smart Glasses in Seven Months, each "ban" turned out to be a particular restriction with a particular reason, not a blanket prohibition; when a UK Comic-Con banned smart glasses, the same device stayed perfectly legal everywhere else. The pattern here is identical. The film was rated, released and watched. One image, in one kind of place, near one nursery the rulebook forgot, was told to come down.
Sources and verification
This article is built on the ASA's published ruling on Warner Bros Entertainment UK Ltd, complaint reference G26-1336668, dated 5 August 2026, read in full. Every figure, quotation and finding above — the one-of-four split, the "realistic impression of a dead child" wording, the 7.30pm scheduling that cleared the trailers, the children's viewing index of 31, the nursery visibility and the schools-not-nurseries gap in the buffer — is taken from that document. The posters were found in breach of the CAP Code rules on social responsibility (1.3) and harm and offence (4.2); the ASA's own guidance on fear and distress, on children and on film and TV advertising sets out the standards it applied, and Clearcast is the body that cleared the television trailer with the post-7.30pm restriction. The story was first reported by the Guardian; its framing is the one this piece checks against the ruling.
One caution worth recording: a general search for this ruling first returns a different Warner Bros case, reference G26-1335168, concerning the film They Will Kill You, in which all four issues were not upheld. That is a separate ruling and is not the basis for anything here. The correct case is G26-1336668.
The ASA gives no fine, names no nursery, and reports no count of every poster site or any box-office figure, so none is stated here. Warner Bros's account of its design intent — the "living mummy," the blue eye "connoting life" — is reported as the studio's argument to the regulator, which the regulator did not accept on the placement point.
