‘Werwulf’ ARG Drops Its Second Clue: Scan the Real Full Moon With a Snapchat Lens to Reveal the Next Sign

Few directors treat marketing like a ritual the way Robert Eggers does. His films arrive wrapped in folklore, period detail and a general sense that something ancient is watching. With ‘Werwulf,’ his medieval werewolf horror, the campaign has taken that idea literally by tying itself to the lunar calendar.

The film comes from Focus Features and reunites Eggers with ‘Nosferatu’ collaborators Aaron Taylor-Johnson, Lily-Rose Depp and Willem Dafoe, with Ralph Ineson also in the cast. Eggers co-wrote the script with Sjón, who worked with him on ‘The Northman.’ It arrives in theaters on Christmas Day, continuing a holiday tradition after ‘Nosferatu’ opened with a $40 million Christmas debut and went on to become Eggers’ highest-grossing film.

Now the studio has opened the next stage of its alternate reality game. The second clue for the ‘Werwulf’ ARG is live, and it asks fans to point their phones at the real full moon.

The game lives at DevourethAllMankynde.com, named for the tagline on the film’s July poster. It is synced to the three full moons between September and November. On each one, fans must find a hidden sign on various digital platforms, decipher it and enter the answer on the site.

The catch is that each sign is only available for 24 hours before it vanishes. Players who complete all three moons are promised a mysterious prize.

For the October full moon, known as the Hunter’s Moon, Focus Features has launched a Snapchat lens. It allows fans to scan the actual full moon, which then reveals the next sign. The lens opens with the ‘Werwulf’ title in blackletter type and the line “Only in Theaters This Christmas.”

The first clue was hidden on the film’s account on X and used the Theban alphabet, sometimes called the witches’ alphabet. According to a fan guide, the answer pointed to the Hunter’s Moon, which peaks on Monday, October 26. Focus Features also scheduled the second clue to be solvable from Sunday evening Pacific time.

The second clue for the ‘WERWULF’ ARG is now live. Focus Features has launched a Snapchat lens that allows fans to scan the actual full moon tonight, which will reveal the next sign. The mysterious prize will be revealed at the November full moon. 🔗: https://t.co/iwknrWw2IZ https://t.co/Jxr1J0EoId

The lunar theme has been consistent. The first trailer arrived on June 29, the poster on July 29 and the first merch on August 28, and the second trailer landed on September 26 on the Harvest Moon. The remaining full moons before release are October 26, November 24 and December 23, and the pattern suggests something will happen on each.

Focus has also taken the campaign into the real world. A Full Moon Pop-up at The Brig in Venice, California, on October 25 featured exclusive merchandise. Eggers told press this fall that the transformation shot in the trailer is not the big one, and that the real scene is still being held back.

The studio has not revealed what the reward is, and the prize will be revealed at the November full moon. The game’s on-screen text says a rare reward awaits those who fulfill all three moons. It adds that rewards are limited, vary by location and are only available to people aged eighteen or older.

That means fans will need to act quickly, and not everyone who solves the puzzles will necessarily receive a prize. It also gives the campaign a sense of scarcity that suits a horror release.

The film is described as a harrowing tale of devotion, damnation and the devil within, and the trailers have deliberately hidden the creature itself. Taylor-Johnson plays a man haunted by a terrifying transformation, and the trailers include a family curse and a hunter played by Dafoe. Newcomers Bodhi Rae Breathnach, Jack Morris, Jan Bijvoet and Ritchi Edwards round out the cast.

Eggers has said he drew heavily on medieval accounts of werewolf lore, and he originally planned to shoot in black and white before choosing color. The film is produced by Eggers, Sjón, Working Title’s Tim Bevan and Eric Fellner and others, with Maiden Voyage’s Chris and Eleanor Columbus as executive producers.

Alternate reality games succeed when they reward curiosity, and this one does so by tying the puzzle to something real. Scanning the actual sky is a small, memorable moment, and it makes the film feel like part of the world rather than an ad. With 2 more moons to go, the community has plenty of time to keep decoding.

By the time the November moon arrives, fans will finally learn what the prize is. Until then, the hunt continues.
