Ethel Cain Joins Robert Eggers’ “Werwulf” Soundtrack: Release Date, Music and Everything We Know
Ethel Cain will contribute an original song, “Wynter Waxeth,” to Robert Eggers’ Werwulf soundtrack. The track is co-credited with composer Robin Carolan, and the full soundtrack is scheduled for digital release on December 18, 2026—one week before Focus Features opens the film in U.S. theaters on December 25.
According to Film Music Reporter, the soundtrack will contain two versions of “Wynter Waxeth.” The release gives Cain a defined musical role in Eggers’ next film: PHANTASMAG reports that it is her first original composition written specifically for a film.
“Wynter Waxeth” Is Ethel Cain’s First Original Song Written for Film
“Wynter Waxeth” is co-credited to Ethel Cain and Robin Carolan, and Film Music Reporter says the Werwulf soundtrack will contain two versions. Carolan is composing the soundtrack and previously scored Robert Eggers’ The Northman and Nosferatu.
PHANTASMAG identifies the track as Cain’s first original composition written specifically for a film. The report does not specify the collaborators’ respective writing, production or performance roles, nor does it say where the song appears in the film or whether either version is used during it.
As a standalone release, “Wynter Waxeth” is expected on November 13, 2026, ahead of both the Werwulf soundtrack and the film, according to PHANTASMAG.
Robin Carolan’s Score and Two Song Versions
Carolan’s joint credit on “Wynter Waxeth” places the song within the wider musical framework of the Werwulf soundtrack, rather than presenting it as a separately credited placement. According to Film Music Reporter, Carolan is composing the soundtrack, continuing a working relationship with Eggers that includes scores for The Northman and Nosferatu.
The soundtrack is set to include two versions of “Wynter Waxeth.” At present, no supplied release information identifies those versions by title, describes their arrangements or confirms their screen placement. That leaves the two-version listing as a useful concrete detail for listeners, but not evidence of an alternate mix, reprise, score adaptation or separate performance.
The soundtrack rollout distinguishes Carolan’s score credit from the Cain-Carolan song credit, confirming both while leaving the complete track list and further session or personnel details unavailable.

Sacred Bones’ Soundtrack Rollout Arrives Before the Film
The complete Werwulf soundtrack is scheduled for digital release on December 18, 2026. CD and vinyl editions are planned through Sacred Bones Records, Film Music Reporter states. No specific physical-release date, format configuration or preorder information is included in the reported announcement.
That schedule puts the album seven days ahead of the film’s U.S. theatrical opening. The November 13 expected standalone release of “Wynter Waxeth” would precede the digital soundtrack by just over a month, creating a staggered sequence of song, score album and theatrical release.
Sacred Bones’ planned physical editions are the only confirmed physical formats in the available reporting. Until the label or film’s representatives provide additional details, there is no basis to infer bonus tracks, exclusive variants or a broader release plan.
Robert Eggers’ Werwulf: Release Date and Confirmed Cast
Focus Features lists Werwulf for a U.S. theatrical release on December 25, 2026. Robert Eggers directs the film, which stars Aaron Taylor-Johnson, Willem Dafoe and Lily-Rose Depp.
With Carolan returning after The Northman and Nosferatu, and Cain bringing an original co-written song to the project, the confirmed music credits give Werwulf a soundtrack rollout with its own lead-in before the Christmas Day opening. The next scheduled milestone is the expected November 13 release of “Wynter Waxeth.”
