Prime Video’s adaptation of Lucy Score’s Things We Never Got Over has added six performers to its growing Knockemout ensemble. Sean Teale will play Lucian, Sarah Jeffery has been cast as Sloane, Megan Stott will portray Waylay, Lili Simmons joins as Lina, Anthony Keyvan plays Stef, and JoBeth Williams will appear as Liza J.

The newcomers join previously announced leads Molly Griggs, Matthew Noszka and Tommy Martinez. Griggs plays Naomi Witt, while Martinez and Noszka play brothers Nash and Knox Morgan, respectively. The casting expansion gives the series more of the community around its central romantic and family story—an important proposition for a show set in a deliberately distinctive small town rather than one confined to a single couple’s orbit.

The newly announced cast

  • Sean Teale as Lucian — Teale’s previous credits include Doctor Odyssey and Only Murders in the Building.
  • Sarah Jeffery as Sloane — Jeffery has appeared in The Six Triple Eight and Charmed.
  • Megan Stott as Waylay — Stott’s credits include Penelope and Little Fires Everywhere.
  • Lili Simmons as Lina — Simmons has appeared in Double Down South, Power Book IV: Force and Bone Tomahawk.
  • Anthony Keyvan as Stef — Keyvan’s recent work includes Just Picture It and XO, Kitty.
  • JoBeth Williams as Liza J. — Williams’ credits include Poltergeist and Behemoth!.

No additional character details for the six roles have been provided. That distinction matters: the role names establish who has been cast, but they do not by themselves confirm the size of each part, the characters’ season-long arcs, or how closely individual plot beats will follow the novel.

What the series is about

The official premise follows Naomi Witt, a runaway bride who arrives in the Virginia town of Knockemout intending to help her estranged twin and then return to the life she abandoned. Instead, Naomi’s sister disappears. Naomi is left responsible for a niece she did not know she had, while the town introduces her to an array of personalities—including local sheriff Nash Morgan and his gruff brother, Knox.

That setup puts several pressures on Naomi at once: the unresolved circumstances behind her arrival, a fractured relationship with her twin, sudden caregiving responsibility and an unfamiliar community that is not content to stay in the background. The series’ basic engine is therefore broader than a romance alone. It has family separation, a sudden change in domestic responsibility and a newcomer’s attempt to find footing in a town whose residents are positioned as central to the story.

Griggs taking on Naomi and her estranged twin is also a key piece of the adaptation’s premise. The official description explicitly identifies both women with Griggs, meaning the production will need to convey two connected but separate characters through one performer. Beyond that foundation, the available details do not establish how the series will stage or structure the twins’ story.

Why six supporting roles are significant

Analysis: Adding six named roles at this stage signals that Knockemout is being built as an ensemble setting, not merely a backdrop for Naomi, Knox and Nash. A small-town romantic drama depends heavily on recurring relationships: friends, relatives, coworkers and local figures can keep storylines moving even when the central pair are not sharing a scene. The cast announcement identifies Lucian, Sloane, Waylay, Lina, Stef and Liza J. as characters the adaptation considers substantial enough to name publicly.

That does not guarantee that every character will receive equal screen time. It does, however, make the ensemble a more concrete part of the show’s identity. For readers familiar with Score’s fictional setting, the announcement offers early confirmation that the adaptation is populating Knockemout beyond its three announced leads. For viewers coming to the series without the books, it points to a story designed around an interconnected community.

The casting also arrives with a range of performers whose cited credits span television and film. That is context, not a prediction of tone: past projects do not tell audiences how a performer’s new character will be written. Still, the mix underscores that the show is assembling a multi-generational group around the central cast.

The creative team behind Knockemout

Things We Never Got Over is the first of three books in Score’s Knockemout series. Eric Charmelo and Nicole Snyder wrote the pilot and will serve as showrunners and executive producers. A showrunner is the senior creative leader of a television series, generally responsible for guiding the writing and overall storytelling while also helping oversee production decisions. In practice, having the pilot writers as showrunners can provide continuity between the episode that establishes the series and the team steering its larger direction.

Gina Girolamo is an executive producer through Strega Stories, while Score is also an executive producer. Amazon MGM Studios is producing. An executive producer credit can cover different responsibilities depending on a production, so the announcement does not define the specific day-to-day involvement of every credited producer. Score’s credit does establish that the novelist has an official producing role on the adaptation.

The show was announced in June, and this latest update is a casting report rather than a release-date announcement. There is no premiere date, episode count or confirmed production timetable in the information currently available. Similarly, the announced material does not state whether the series will adapt only the first book or establish a plan for the wider trilogy. Those are separate questions from the fact that the source material itself comprises three books.

Book adaptations and the expectations around casting

Adaptations of popular novel series have become a major part of streaming’s scripted-TV mix. Prime Video already has series adapted from books including Reacher, The Summer I Turned Pretty, Bosch, Scarpetta, Off Campus and We Were Liars. That context does not reveal how Things We Never Got Over will be structured, but it places the show within an established approach: using a novel’s existing characters and setting as the base for an episodic screen story.

For book-to-screen projects, casting updates carry particular weight because a character name is often the first tangible bridge between readers’ imaginations and the show’s version of the material. It is also worth separating confirmed information from assumptions. This announcement confirms actors and role names. It does not confirm costumes, visual design, episode-specific events, romantic pacing, deviations from the book or any unannounced casting.

That distinction is useful because serialized television works differently from a novel. A screen series must distribute character information across scenes and episodes, create roles for an ensemble to interact with, and decide what material belongs on screen versus what can remain implied. None of that automatically means an adaptation is more or less faithful; it means the medium has its own storytelling demands.

What remains unconfirmed

The six additions provide the clearest new picture yet of the people who will inhabit Knockemout, but much of the production remains under wraps. There are no confirmed details on when filming begins or ends, when the show will arrive on Prime Video, how many episodes it will have, or whether more cast members are still to be announced.

For now, the confirmed core is Naomi’s disruptive arrival in Knockemout, the vanished twin and newly discovered niece she leaves behind, and the Morgan brothers who become part of Naomi’s unexpected future. Teale, Jeffery, Stott, Simmons, Keyvan and Williams now join that foundation as the adaptation moves from its initial lead casting toward a fuller version of the town.
