Coffin Moon TV Series: Paramount Is Adapting Keith Rosson’s Vampire Novel

News | September 29, 2026

Keith Rosson’s Coffin Moon is being developed for television. The novel follows a Vietnam veteran and his teenage niece through a blood-soaked pursuit of the vampire who destroyed their family. It has a specific place and time, Portland and the Pacific Northwest in the winter of 1975, and a human conflict that should matter as much as the fangs.

According to Deadline’s September 22 report, Paramount Television Studios is developing the series with Iron Ocean, the production company run by Jessica Biel and Michelle Purple. Noah Harpster and Micah Fitzerman-Blue are attached to adapt and showrun it, and Rosson will be a consulting producer.

That is the confirmed development news. There is no announced cast, premiere date, series order, or streaming homeas of September 29. Biel’s involvement as a producer does not mean she has been cast in the show, and a Paramount studio project is not automatically a Paramount+ release.

What is Coffin Moon about?

Random House’s description of the novel introduces Duane Minor, a Vietnam veteran working as a bartender in 1975 Portland. He is trying to stay sober, preserve his marriage to Heidi, and help raise his thirteen-year-old niece, Julia. Their uneasy attempt at a stable family life collapses when Duane crosses John Varley, a vampire who retaliates by killing Heidi.

Duane and Julia set out after Varley, and the chase takes them beyond Portland through the Pacific Northwest. They encounter other threats and people caught in the vampire’s orbit. The premise has the momentum of a pursuit thriller, but its central question is what grief and revenge do to the surviving family members.

That distinction could make the adaptation stand out. Varley is a terrifying target, yet Duane and Julia have to live with the loss that started their hunt. Catching a monster cannot simply restore their old lives. The book’s 1970s setting also gives the story a world of bars, highways, winter weather, and uneasy postwar homecomings rather than a timeless Gothic backdrop.

Who is making the TV adaptation?

Deadline reports that Paramount Television Studios and Biel and Purple’s Iron Ocean are developing the project through Iron Ocean’s first-look deal with the studio. Harpster and Fitzerman-Blue, whose credits include A Beautiful Day in the Neighborhood and Painkiller, are attached to develop, adapt, and serve as showrunners. Rosson’s consulting-producer role connects the author to the production, though the scope of his creative input has not been detailed publicly.

Those attachments are meaningful, but the show remains in development. A development announcement identifies a project and its creative team; it is not a guarantee that filming has begun or that a finished season has been ordered. The next substantial milestones to watch for are a network or streaming buyer, a formal series order, casting, and a production start.

Will Jessica Biel star in Coffin Moon?

There is no casting announcement for Biel or for Duane, Julia, Heidi, or Varley. Biel and Purple are involved through Iron Ocean as producers. Some headlines have blurred that difference, but the reported deal does not name Biel as a performer.

Likewise, there is no reason yet to assign the series to Paramount+. Paramount Television Studios is the studio developing it; the eventual distributor or platform has not been confirmed. A release year would be speculation at this stage.

Why this vampire story could work as a series

The novel’s chase has a clear objective, which gives a potential season forward motion. It also has room for the quieter consequences of violence: Duane’s attempts at sobriety, his bond with Julia, and the question of whether their shared mission is bringing them together or consuming them. A television adaptation could take time with both sides of that story, although no episode count or narrative plan has been announced.

Rosson himself described the book as “True Grit with vampires” in an interview with The Beat. He discussed combining horror with crime fiction and said that strengthening the emotional connection between Duane and Julia was central to revising the novel. That is a useful way to understand its appeal: the monster hunt supplies the plot, while the family relationship gives it weight.

There is also a potential trap for the adaptation. Expanding Varley’s mythology or adding action might be tempting over multiple episodes, but the book’s distinctive tension comes from keeping the human cost visible. That is an editorial expectation based on the novel and Rosson’s account of writing it, not a description of an announced screenplay.

When was the book published?

Coffin Moon first appeared in hardcover and ebook on September 9, 2025. Random House released the U.S. paperback on September 22, 2026, the day the television development news broke. The publisher lists the book at 320 pages and also offers an audiobook. Readers who want to discover Duane, Julia, and Varley before casting and plot changes are announced can start with the novel now.

Rosson is also the author of Fever House and The Devil by Name. Readers who enjoy his mix of crime, horror, and damaged family relationships may find those books a natural next stop, though Coffin Moon is the specific novel being adapted in this announcement.

Coffin Moon TV series: What is confirmed?

The prospect of Coffin Moon on television is exciting because its vampire is only part of the danger. Duane and Julia’s pursuit has the shape of a thriller, but the lasting story is about the cost of giving grief a target. For now, the novel is available and the screen version remains a project to watch, with its cast, platform, and production schedule still to be confirmed.
