originating from a concept developed by Darrow, which he described as "Doc Savage meets Citizen Kane". In 2009, it was announced that the Wachowskis and Circle of Confusion were producing an animated feature of Shaolin Cowboy, subtitled Tomb of Doom, written and co-directed by Darrow, and animated by Madhouse. Darrow spent a year living in Japan and working on the production which was halted after the American financiers, The Weinstein Company, backed out. Around half of the footage was finished, and some of the completed scenes and pencil tests were shown at San Diego Comic Con in 2012 and Chicago Comic & Entertainment Expo in 2015. The film was supposed to feature a sequence animated by Masaaki Yuasa. In 2012, Shaolin Cowboy resumed publication at Dark Horse with a 96-page book stylized as a pulp magazine containing a Shaolin Cowboy prose story written by Andrew Vachss (with whom Darrow has had a working relationship dating back to the early 90s) with spot illustrations by Darrow, a prose story by Michael A. Black with spot illustrations by Gary Gianni and one-page strips written and drawn by Darrow. The book was followed by The Shaolin Cowboy, a four-issue mini-series subtitled Shemp Buffet for the collected edition, and The Shaolin Cowboy: Who Will Stop the Reign?, another four-issue mini-series, which incorporated some the visual ideas from the unfinished animated feature. In 2015, DC Comics announced Darrow as the artist for the supplemental mini-comic to the third issue of Frank Miller and Brian Azzarello's The Dark Knight III: The Master Race, as well as the variant covers for issues 3 and 4, though none of his contributions were ultimately realized. Meanwhile, Dark Horse issued a press release announcing the first English-language collection of the Bourbon Thret strips, to be partially re-colored by Dave Stewart. Since then, Dark Horse has re-released Hard Boiled and The Big Guy and Risty the Boy Robot with new coloring by Stewart as well as the entirety of Shaolin Cowboy in a uniform format. As of 2019, the Bourbon Thret collection still hasn't been released. Over the course of his career, Darrow has contributed storyboards and conceptual designs for a number film productions, many of which ended up cancelled, including J. J. Abrams' Superman: Flyby, an animated feature by Ridley Scott, one of Hollywood's attempts at adapting Akira and Alex Proyas' adaptation of Paradise Lost. Outside of comics and film,
