Nathan Fillion’s Dark New Mystery Series Officially Getting Film Adaptation

Published Nov 10, 2026, 11:05 AM EST Grant Hermanns is a TV News Editor, Interview Host and Reviewer for ScreenRant, having joined the team in early 2021. He got his start in the industry with Moviepilot, followed by working at ComingSoon.net. When not indulging in his love of film/TV, Grant is making his way through his gaming backlog and exploring the world of Dungeons & Dragons with friends. Nathan Fillion is already eyeing another major adaptation with Witness Point. Penned by Fillion with DC veteran Heath Corson, the four-part miniseries is centered on a rural Wisconsin town known as Baraboo as they learn that many of them are members of the Witness Protection Program, creating an air of paranoia around them, all the more complicated when a U.S. Marshal's body is found decapitated. Published by Dark Horse Comics, Witness Point's current final chapter is set to arrive on November 25, but won't be the end. During an appearance on the Patton Oswalt-hosted Comic Creators Block Party livestream, Fillion revealed that he just sealed a deal to bring Witness Point to life with a film adaptation at Lionsgate. Joined by his co-creator Corson and artist Soo Lee, the co-creator/actor cautioned that development is still in its early days at the studio, but that the team are all excited about the project, and even teased ideas being discussed to expand the source material: Nathan Fillion: We sold the book, we’re going to see how it goes from there, to Lionsgate. We’re very excited. This is the thing, this plot, this idea, this whole concept is an engine that will keep this thing running. It’s got nothing but potential. You could go deep, you could go layers deep, flashbacks to the past, are you kidding?! Witness Point marked a notable change of pace for Fillion as it became his first venture into comic book writing. The timing ultimately proved serendipitous for the Emmy nominee as he started ramping up his appearances as the Guy Gardner variant of Green Lantern in the James Gunn-led DC Universe, while also having voiced a variety of Marvel and DC characters in animated projects throughout the years. Moreover, Witness Point's film adaptation development is now coming as Fillion's aforementioned DCU future is in doubt amid Gunn and Peter Safran's exit from DC Studios as Co-CEOs. Reports are still varying on the nature of their departures, and the ultimate plan for the future under Jeremy Latcham's leadership. However, the latest comments from sources point to another reboot being on the horizon, potentially making the Superman sequel Man of Tomorrow and the animated Mister Miracle series his final outings as Gardner. Witness Point getting a film adaptation also comes at an opportune moment as small town mysteries continue to be popular on screen. MGM+'s From has earned widespread acclaim across its first four seasons, which just debuted on Netflix to massive streaming numbers. Additionally, while not quite as breakout successes as their contemporaries, Bob Odenkirk's Normal, for which Fillion's comic is sure to evoke memories of, and Aaron B. Koontz and Luke Boyce's Revival were both critical hits. Fillion's confirmation that Dark Horse Comics, likely through their Dark Horse Entertainment banner, is partnering with Lionsgate for the Witness Point adaptation marks a notable twist for the studios as being their first time collaborating in seven years. The banners' first proper team-up came with the 2019 reboot of Mike Mignola's Hellboy, led by David Harbour, which infamously became a critical and commercial disaster amid varying reports of production troubles. Choose the movie with the higher Rotten Tomatoes score. The other big question now surrounding the Witness Point film is how involved Fillion will be in its production. The Emmy nominee has stayed quite busy in recent years between both ABC's Rookie franchise and his various DC projects, potentially taking him out of the running for starring as the comic's central character, Sheriff "Kite" Calhoon. However, with him now having made his debut on the writing side of things for the comic, and being invested in its future, there's still a chance Fillion will lead the charge on screen for his series' adaptation.
