Netflix’s 10-Part Sci-Fi Thriller Series Has One Of Its Best Casts

Netflix has built a reputation for attracting major stars to its original projects, turning big-name casting into a powerful marketing tool. From prestige dramas to blockbuster movies, the platform consistently proves it can compete with traditional studios for A-list talent. That’s exactly why it’s so surprising that Maniac, despite its stacked cast, isn’t talked about more often.

Released in 2018, Maniac is a mind-bending sci-fi thriller that blends psychological drama with surreal world-building led by A-List powerhouses Emma Stone and Jonah Hill. The story follows Annie (Stone) and Owen (Hill), two strangers who take part in a mysterious pharmaceutical trial promising to fix their minds with a guarantee of no adverse side effects. Of course, things don’t go according to plan.

While Emma Stone and Jonah Hill headline the Netflix miniseries, they are far from the only standout performers in Maniac. The show boasts a lineup filled with award winners and nominees across the Academy Awards, Golden Globe Awards, and Primetime Emmy Awards. Even beyond its cast, Maniac delivers a unique experience that makes its under-the-radar status all the more baffling.

Emma Stone And Jonah Hill Give Career Best Performances In Maniac

A-List Leads Elevate A Surreal Story Into Something Deeply Human

At the center of Maniac are Emma Stone’s Annie Landsberg and Jonah Hill’s Owen Milgrim, two deeply troubled individuals searching for relief from their inner struggles. Annie is battling addiction and unresolved trauma, while Owen wrestles with schizophrenia and a fractured sense of reality. Annie and Own’s emotional journeys form the backbone of the show, helped in no small part by the incredible performances Stone and Hill deliver.

For her part, Emma Stone delivers a layered, vulnerable performance in Maniac that stands among her best work. She brings a raw intensity to Annie, balancing cynicism with fragile hope. It’s a performance that feels both grounded and unpredictable, one that saw her nominated for both a Satellite and Screen Actors Guild Award.

Alongside her is Jonah Hill, who gives one of the most restrained performances of his career. Often associated with comedies like Superbad, in Maniac Jonah Hill leans fully into Owen’s quiet desperation. His portrayal is subtle yet deeply affecting, proving his dramatic range in a way that rivals his work in Moneyball or Don’t Worry, He Won’t Get Far On Foot.

The chemistry between Stone and Hill is a particular strength of Maniac, and shows just how much of a masterstroke casting both in the lead roles truly was. Having previously worked together, their dynamic feels natural, even as their characters navigate increasingly bizarre scenarios. Whether they’re in a noir-inspired fantasy or a suburban dreamscape, their connection remains believable.

Even beyond its leads, Maniac features an impressive supporting cast full of faces that many viewers will instantly recognize. Justin Theroux’s Dr. James K. Mantleray is a chaotic presence, with Theroux bringing eccentric energy to the role. For audiences watching today he’s also known for playing Mr. House in Fallout, and his performance in Amazon Prime’s post-apocalyptic sci-fi is already driving more viewers to discover Maniac thanks to exploring Theroux’s filmography.

The cast also includes Gabriel Byrne, a Golden Globe Awards winner and Primetime Emmy Awards nominee, whose understated performance as Milgrim adds both tension and gravitas. Meanwhile, two-time Academy Award Best Actress winner Sally Field brings her legendary abilities to round out the cast as Dr. Greta Mantleray. Then there’s Sonoya Mizuno, known best as Mysaria in House of the Dragon, who provides a calm counterbalance to the chaos as Dr. Azumi Fujita.

The recurring cast also includes the likes of The Simpsons veteran Hank Azaria, The Wire star Leo Fitzpatrick, and Golden Globe winner and Ozark staple Julia Garner. Together, this ensemble elevates Maniac into something far more compelling than its premise alone might suggest, and makes it baffling that it’s somehow faded into obscurity over the years since its 2018 release.

Maniac Has Much More To Offer Than A Great Cast

The Netflix Minieries Stands Is A Visually Inventive And Emotionally Rich Sci-Fi Experience

While its cast is a major draw, Maniac stands out for several other reasons. Visually, the series is striking, blending retro-futuristic aesthetics with dreamlike sequences that shift between genres. Each episode feels distinct, yet they all contribute to a cohesive and immersive world.

The storytelling is equally ambitious. Rather than following a traditional narrative structure, Maniac explores multiple realities shaped by the characters’ subconscious minds. The show uses its premise to delve into identity, trauma, and human connection in unexpected ways. There’s significant thematic depth to the story, which is likely why Hill and Stone signed on in the first place.

Another strength of the show is its tone. The premise could suggest either something incredibly bleak or insufferably wacky if mishandled, yet Maniac manages to avoid being either. The series balances dark themes with moments of humor and warmth, perfectly balancing both to create an incredibly emotionally immersive viewing experience. This versatility keeps the story engaging, even as it tackles complex psychological concepts.

However, above all else, the main reason this underrated show deserves more attention is just how well it resonates. At its core, Maniac is about healing and connection. Despite its sci-fi framework, the emotional stakes feel deeply real. Annie and Owen’s journey is incredibly relatable because it reflects universal struggles. The conceptual sci-fi is simply a vehicle to carry what is an incredibly human story.

With its inventive storytelling, striking visuals, and emotionally rich narrative, Maniac proves it is far more than just a star-studded series. It’s a bold, original project that deserves far more recognition within Netflix’s catalog, and still would do even without a cast led by Emma Stone and Jonah Hill.
