Sony Pictures hires Jill Blankenship to write medieval action film ‘Castle,’ developed from Chris Bremner’s Unknown Quantity idea
Jill Blankenship has been tapped to pen Sony Pictures’ medieval action project “Castle,” originating from an idea by Chris Bremner through his company Unknown Quantity, with Bremner and Jeff Arkuss set to produce.
Sony Pictures has hired writer Jill Blankenship to pen “Castle,” a medieval action feature based on an original idea from Chris Bremner’s Unknown Quantity, according to an announcement published by Deadline on Aug. 3, 2026.
The project is being developed as a film treatment, with the movie’s plot details being kept under wraps at this stage. Deadline did not provide a release date, director, cast, or additional production timeline details.
Deadline described “Castle” as a medieval actioner, positioning Blankenship as a leading writer attached to the script during development. The report also framed the assignment as a move from television into feature film writing, though it did not name which TV series Blankenship is associated with or describe the specific scope of that transition.
Chris Bremner, whose Unknown Quantity is the source of the idea, will produce “Castle.” Deadline further said Bremner’s producing partner Jeff Arkuss will also serve as a producer on the project, and that Arkuss was instrumental in connecting the deal for the film’s development.
The announcement did not specify whether Blankenship’s contract includes additional writing rounds, whether the project is tied to a particular franchise or property, or whether Sony Pictures has finalized internal creative or production leadership beyond the writer and the producing team.
As of the publication of the Aug. 3 report, “Castle” remains in the early development stage, with key elements such as storyline specifics, casting, and the director not yet publicly identified. Sony Pictures and the attached producers have not publicly outlined production start dates or any delivery milestones in the Deadline report.
For studios, attaching a writer and identifying producer teams are key early steps in narrowing creative direction, aligning budgets, and setting development workstreams before formal greenlighting decisions are made, even when plot specifics remain undisclosed.
Why It Matters
- A major studio attachment of a writer and producing team can report momentum in feature development even when plot and casting are not yet public.
- Blankenship’s move into a medieval action feature reflects ongoing cross-development between television talent and theatrical projects.
- The producer teams centered on Unknown Quantity create a defined creative ownership structure early in the process, which can affect subsequent script and production decisions.
- Because “Castle” is at the script-development stage with details withheld, public information will likely expand later through standard industry updates such as hiring a director and announcing cast or production milestones.
