ABC has ordered a drama pilot for Rabbit, a U.S. adaptation of the BBC One mystery series Ludwig. The project puts an unusually puzzle-minded protagonist at the center of a missing-person investigation: Mark, a reclusive puzzle writer who is known as Rabbit, takes the place of his homicide-detective twin after the brother disappears.
That premise makes the identity swap more than a simple undercover device. Mark’s decision to pose as his brother places someone accustomed to a solitary, cerebral life inside the Cambridge, Massachusetts, police department. While trying to uncover what happened to his twin, he discovers that his skill at resolving seemingly impossible puzzles can make him a highly effective—if unconventional—crime solver.
The order is for a pilot, meaning an initial episode intended to establish the characters, setting and ongoing engine of a prospective series. It is a significant early step, but it does not by itself mean Rabbit has been ordered to series, scheduled, cast or given a premiere date. Those details have not been provided.
What ‘Rabbit’ is adapting
Rabbit is based on Ludwig, which debuted on BBC One in 2024. The British show’s second season aired in 2026, while a third season and a Christmas special are in development. Ludwig stars David Mitchell alongside Anna Maxwell Martin, who plays Lucy.
An adaptation does not necessarily mean a scene-for-scene recreation. The information currently available establishes the shared central idea—a withdrawn puzzle specialist taking on a missing detective twin’s identity—but also identifies an American setting in Cambridge, Massachusetts. Beyond that basic setup, there are no confirmed details on how closely the pilot will track the original series, which characters from Ludwig may have counterparts, or whether the procedural structure will change for U.S. television.
The core concept has two natural story tracks. First is the personal mystery: Mark needs to find out why his brother vanished. Second is the case-of-the-week potential created by a police department realizing that its apparent detective has a rare gift for decoding clues and patterns. The tension is built into the disguise. Every solved case could bring Mark closer to answers, but the same work may also increase the risk that someone notices he is not the detective he claims to be.
The creative team behind the pilot
Megan Ganz and Humphrey Ker are co-writing Rabbit and will serve as executive producers. Ganz’s previous writing work includes It’s Always Sunny in Philadelphia, Mythic Quest, Modern Family, Community and The Last Man on Earth. Ker has written for Mythic Quest and Saturday Night Live UK, and his acting credits include Mythic Quest, It’s Always Sunny in Philadelphia, Curb Your Enthusiasm, American Auto and the docuseries Welcome to Wrexham.
That combination is notable for a project whose lead is defined by both isolation and problem-solving. Ganz and Ker have backgrounds that include comedy, character work and ensemble television, while Rabbit is described as a drama. That does not confirm its exact tone; no official description labels it a comedy-drama or specifies how humorous it will be. Still, the source material’s premise leaves room for the friction between Mark’s private habits and the public demands of a police unit.

Jon Steinberg and Dan Shotz are also executive producers. Steinberg is a co-creator, executive producer and showrunner of Percy Jackson and the Olympians, with Shotz also serving as an executive producer on that series. The pair’s previous work also includes The Old Man and Black Sails.
In television, an executive producer is a senior creative or production credit, but responsibilities can vary from project to project. The announced credits confirm that Ganz, Ker, Steinberg and Shotz are part of the leadership group on the pilot; they do not, on their own, define who would hold which day-to-day role if the project moves forward as a series.
Original ‘Ludwig’ creatives remain involved
Ludwig creator Mark Brotherhood is attached as an executive producer, as are Big Talk’s Kenton Allen and Ludwig star David Mitchell. Their involvement gives the adaptation a direct link to the original production and its leading performer, though it should not be read as a casting announcement for the U.S. pilot. No cast for Rabbit has been announced.
Mitchell’s executive-producer role is especially distinct from an on-screen commitment. The available information identifies him as a producer on the new pilot and as a star of the British series, but it does not say that he will appear in Rabbit. Likewise, there is no announced actor for Mark or for the missing homicide detective twin.
20th Television is the studio behind the pilot. Ganz is under an overall deal at the studio. An overall deal generally connects a writer or producer with a studio for development work; here, it explains the studio relationship but does not provide further information about the pilot’s production timetable.
Why the pilot’s setup has a sturdy TV engine
Procedural mysteries often need a repeatable reason for their lead character to encounter new cases. Rabbit has one in Mark’s unexpected ability to solve puzzles that stump other people. The personal search for his brother supplies the larger serialized question—the ongoing mystery that can develop across episodes—while individual investigations can provide immediate problems for Mark to crack.
The twin premise also raises practical dramatic stakes without needing additional mythology to be established at the outset. Mark must inhabit a job he did not previously hold, interact with colleagues who knew his brother, and plausibly maintain the impersonation long enough to find useful evidence. His puzzle-writing background is not merely a colorful occupation: it is the stated reason he becomes valuable in criminal investigations.
“Impossible puzzles” should be understood as a character and story description rather than a promise about a particular kind of game mechanic. Nothing has been announced about exact types of cases, forensic methods, a recurring villain, episode count, or whether viewers will be invited to solve clues alongside Mark. The confirmed hook is simply that his unusual analytic ability turns him into an unlikely crime-solving success.
For viewers following other developing television projects, the pilot joins a wider slate where recognizable performers and formats can shift dramatically between seasons and series; see also Jennifer Coolidge’s reported return for The Watcher season two.
What has—and has not—been confirmed
- Confirmed: ABC has ordered a pilot for Rabbit.
- Confirmed: The pilot is based on BBC One’s Ludwig.
- Confirmed: Mark is a puzzle writer called Rabbit who impersonates his missing homicide-detective twin in Cambridge, Massachusetts.
- Confirmed: Megan Ganz and Humphrey Ker are co-writers and executive producers; Jon Steinberg, Dan Shotz, Kenton Allen, Mark Brotherhood and David Mitchell are also executive producers.

For now, the clearest promise of Rabbit is its character-based mystery: a man who prefers solitude must convincingly become his brother, work within a police department, and use the puzzle-solving instincts that defined his old life to navigate a far more dangerous new one. Whether that pilot proceeds to a full series remains the next major question.
