Charlotte Kirk and Neil Marshall Reunite for Fifth Collaboration on Psychological Thriller 'The Spiral Down'
Charlotte Kirk and Neil Marshall are teaming up for a fifth film together, this time on a psychological thriller called The Spiral Down, Deadline reported on 13 August 2026.
The pair's working relationship stretches across four previous features: The Reckoning, The Lair, Duchess, and most recently Compulsion. Their fifth collaboration shifts the creative setup in one notable way — Marshall will step back from the director's chair this time. Aaron Mirtes is set to direct The Spiral Down, with Marshall moving into a producing role alongside Kirk and Karlos Ways. Kirk will produce through her company, Primal Empire Studios.
The story itself twists the serial-killer formula into something more layered. A killer obsessed with perfection kidnaps a woman named Mary Doyle, played by Kirk. Detectives on the case then discover that Mary is a dangerous escapee from a psychiatric institution, with a violent past behind her. After she kills her captor and vanishes, the investigation flips entirely — the prey becomes the puzzle at the centre of the case.
Cameras were set to roll in Kentucky, U.S., the month following the announcement — putting production on track for a September 2026 start. Additional casting was still in process at the time of the report, so further names are expected to join Kirk in front of the camera as the shoot approaches.
What makes this pairing worth watching is the sheer consistency behind it. Five films together is rare in an industry where creative partnerships often collapse after one project, and the shift to a new director suggests Marshall and Kirk are looking to stretch their collaboration beyond their established director-actor dynamic. Mirtes taking the reins will give the project a fresh visual and tonal hand, while Marshall's continued involvement as a producer keeps the partnership intact.
Independent genre productions like this — films made outside the major studio system, often with leaner budgets and tighter schedules — have become a reliable pipeline for theatrical and streaming releases alike. The film's Kentucky shoot points to the state's growing appeal as a production location, offering tax incentives and varied landscapes that can double for multiple settings on screen.
With casting still open and a shoot date weeks away, The Spiral Down is early in its journey to screens. But the ingredients — a proven creative partnership, a script that subverts expectations, and a director getting his shot alongside established producers — give it a foundation that genre audiences will note.
