Sam Rockwell as a private investigator with a brain tumor and Maisy Stella as the girl who drags him into a nightmare—Tumor isn’t just another psychological thriller. It’s a descent into the fractured mind of a man racing against his own decay, where every clue might be a hallucination and every ally could be the enemy. Based on the graphic novel by Joshua Hale Fialkov and Noel Tuazon, and directed by Will Bridges (All of You), this film promises to be as emotionally brutal as it is visually striking. But can it avoid the pitfalls of its genre, or will it drown in its own ambition?

The Premise: A PI’s Last Case (If His Brain Lets Him Solve It)
Frank Armstrong (Rockwell) is a down-on-his-luck LA private investigator with a late-stage brain tumor and a penchant for self-destruction. When he’s hired to find the missing daughter of a powerful political figure, he stumbles into a conspiracy that might not even be real. His perception fractures—memories blur with the present, allies turn to enemies, and the line between hunter and prey dissolves.
The real twist? Evie Gibson (Stella), the girl he’s supposed to save, might be the only one who can ground him—or she might be another figment of his dying mind.
Sam Rockwell: The Perfect Actor for a Man Unraveling
Rockwell is one of the few actors who can balance charm, menace, and vulnerability in the same scene. His Frank Armstrong isn’t a tough-guy detective—he’s a man fighting his own body, his confusion and rage making him both sympathetic and terrifying.
Bridges describes the role as a “man unraveling his own past while racing against time”, and Rockwell is the perfect choice to play that desperation. His performance in Moon proved he can carry a film with just his voice and a hologram. Here, he’s got Maisy Stella as his anchor—and that dynamic could be electric.
Maisy Stella: The Wildcard Who Could Steal the Show
Stella, fresh off her breakout role in My Old Ass, plays Evie Gibson, a girl caught in a web of lies—or is she? Bridges compares their chemistry to Jean Reno and Natalie Portman in The Professional—a pairing that’s equal parts tender and explosive.
The key question: Is Evie real, or is she another hallucination in Frank’s deteriorating mind? Stella’s ability to switch between vulnerability and ferocity makes her the perfect foil for Rockwell’s unraveling PI.
Will Bridges: From Romance to Psychological Horror
Bridges made a name for himself with All of You, a romantic drama that topped Apple TV’s charts. Now, he’s taking a hard left into psychological horror—and the shift feels natural.
He cites the graphic novel’s “raw emotional intensity” as the draw, particularly its exploration of memory, mortality, and redemption. The challenge? Balancing the thriller elements with the emotional weight—something Bridges seems determined to pull off.
The Graphic Novel Roots: A Story Built for the Screen
The source material (by Fialkov and Tuazon) is already cinematic—a noir-tinged thriller where every shadow could be a lie. The adaptation leans into that, using Frank’s tumor as a narrative device to blend reality and delusion.
Producer Taplin Lundberg calls the Frank/Evie dynamic “combustible”, with dark humor cutting through the tension. If Bridges nails that balance, Tumor could be something special.
4 Reasons Tumor Could Be 2025’s Darkest Surprise
Why This Thriller Stands Out:
| Reason | Why It Matters |
|---|---|
| Rockwell’s Unraveling PI | A career-best performance in the making—raw, desperate, and darkly funny. |
| Stella’s Breakout Potential | Her Evie could be the year’s most unexpected scene-stealer. |
| Bridges’ Genre Shift | From romance to psychological horror—a bold move that might just work. |
| A Graphic Novel Built for Film | The source material’s noir roots make it perfect for adaptation. |
FAQ
Is Tumor based on a true story?
No, but it feels like it could be. The graphic novel’s psychological depth and noir atmosphere give it a gritty, almost documentary realism.
How does Sam Rockwell’s character compare to his past roles?
Frank Armstrong is closer to Moon‘s Sam Bell—a man fighting his own mind—but with more rage and less solitude. It’s a role that demands vulnerability, and Rockwell delivers.
Will Tumor be more psychological or action-driven?
Psychological, with bursts of violence. Bridges wants the tension to come from Frank’s unraveling mind, not just gunfights or chases.
Could this be Maisy Stella’s breakout role?
Absolutely. If she matches Rockwell’s intensity, Evie could be the role that defines her career.
Final Verdict: A Thriller That Cuts to the Bone
Tumor isn’t just another psychological thriller—it’s a descent into the mind of a man losing his grip on reality, with Sam Rockwell and Maisy Stella as the perfect pair to guide us through the madness.
If Bridges strikes the right balance, this could be 2025’s darkest, most unforgettable film.
