Jon Culshaw Is the Twelfth Doctor in New Big Finish Audio Drama

The impressionist, best known for his work on Spitting Image and Dead Ringers, brings Peter Capaldi’s incarnation to life in a collection of full-cast audio adventures beginning with a Halloween-themed anthology in October 2025.
The announcement, which arrived via an official YouTube trailer on August 29, 2025, marks a significant expansion of Big Finish’s Doctor Who audio lineup.

Jon Culshaw Big Finish Contributions
Jon Culshaw’s association with Big Finish Productions predates his Twelfth Doctor casting. His contributions to the company’s Doctor Who audio range have been substantial, establishing him as a reliable voice talent within the franchise’s extended universe. Prior to landing the central role, Culshaw voiced several notable characters, most prominently Brigadier Lethbridge-Stewart, a foundational figure in UNIT’s history within Doctor Who lore.
The Halloween Audio Drama Release
The inaugural release featuring Culshaw as the Twelfth Doctor is Doctor Who – Halloween: Sea Smoke and Other Stories, a box set containing four full-cast audio adventures. Released in October 2025, the anthology carries a horror-themed focus, fitting the Halloween timing of its release. The production brings together an ensemble cast that spans multiple Doctor incarnations and recurring characters.
Cast members for the Halloween anthology include Stephen Noonan as the First Doctor, Lauren Cornelius as Dodo, Jemma Redgrave returning as Kate Stewart, Ingrid Oliver as Osgood, Paul McGann as the Eighth Doctor, and Jaye Griffiths as Audacity. This interconnected casting approach reflects Big Finish’s strategy of weaving narratives across different eras of Doctor Who history.
The Twelfth Doctor Adventures Series
Following the Halloween release, The Twelfth Doctor Adventures series launches in July 2026, establishing a dedicated home for Culshaw’s portrayal of the character. The series is set between The Husbands of River Song and The Return of Doctor Mysterio, a period that remained unexplored in televised Doctor Who.
The first entry in the series, Run Fast Be Kind: The Second Death, was recorded on October 27, 2025. Written by Alfie Shaw and directed by Lisa Bowerman, the episode features Gwithian Evans as companion Ash Wilton. The narrative involves a mission at the end of time against evils woven throughout history, with the broader Run Fast Be Kind arc suggesting extended storytelling potential.
The October 27, 2025 recording session for Run Fast Be Kind: The Second Death occurred before the public announcement of the series in December 2025, indicating that production began while the Halloween anthology was still in development or recently completed.
Jon Culshaw Impersonations and Spitting Image
Jon Culshaw’s reputation as a master impressionist precedes his Doctor Who involvement. His career has been defined by remarkable vocal versatility, most prominently showcased through long-running appearances on the satirical puppet show Spitting Image and the radio comedy series Dead Ringers. These platforms demonstrated his ability to capture distinctive vocal characteristics with precision, a skill that directly translates to voice acting in audio drama contexts.
Impressionist Background and Casting Connection
The connection between Culshaw and the Twelfth Doctor role traces back to his impressionist abilities. According to official accounts, executive producer Nicholas Briggs approached Culshaw specifically inquiring about his Peter Capaldi impression. This professional inquiry led to the casting decision, recognizing that capturing a living actor’s vocal mannerisms required someone with demonstrated impersonation skills.
Culshaw’s impressionist background also features prominently in the announcement materials for the Halloween audio drama. The YouTube trailer and official communications highlighted his reputation in this field, positioning the casting as a natural fit given the demands of audio-only performance where vocal characterization carries the full weight of character portrayal.
Audio dramas present unique challenges for impersonation because listeners cannot rely on visual cues. Success depends entirely on capturing vocal rhythm, accent patterns, and emotional inflection, skills that Culshaw honed through years of professional impression work on television and radio.
Jon Culshaw’s Doctor Who Audio Drama Role
The audio drama format allows Big Finish to explore Doctor Who storylines that cannot exist within the constraints of television production. For the Twelfth Doctor specifically, this means examining a period in the character’s timeline that remained deliberately vague during the original broadcast. The Husbands of River Song ends with the Doctor promising River Song that their next meeting would be their last, leaving significant narrative space before his subsequent appearances.
Character Portrayal Approach
Official descriptions of Culshaw’s portrayal emphasize the Twelfth Doctor’s defining characteristics: acerbic wit, a tendency toward irritability, and an underlying compassion that surfaces in critical moments. These traits mirror Peter Capaldi’s screen performance while allowing Culshaw the interpretive freedom that audio performance demands.
The characterization reflects what many fans consider the Twelfth Doctor’s most memorable qualities, including his intellectual confidence, occasional abrasiveness, and eventual growth into deeper emotional engagement. Big Finish has historically succeeded in maintaining continuity with televised characterizations while developing fresh interpretive angles suited to audio storytelling.

Background and Why This Casting Fits
The casting of Jon Culshaw as the Twelfth Doctor represents a convergence of practical requirements and creative opportunity. Big Finish has consistently sought voice actors capable of capturing established character personalities without direct visual reference, making impressionist skills valuable assets. Culshaw’s professional background positions him perfectly for this challenge, having demonstrated the ability to sustain character voices across extended performances.
The Doctor Who audio drama format also benefits from Culshaw’s experience in performance without visual support. His work on Spitting Image and Dead Ringers required sustained vocal characterization in radio and television contexts where audiences engage primarily through sound. This preparation translates directly to audio drama requirements, where every nuance must be conveyed through vocal performance alone.
