Marvel's Inhumans, which premiered in 2017, brought the iconic Royal Family from the comic books to the screen. The series features a diverse ensemble of actors portraying superpowered individuals living secretly on the moon. The main cast includes Anson Mount as the silent King Black Bolt, Serinda Swan as Queen Medusa, and Iwan Rheon as the ambitious Maximus.

Primary Cast of Marvel's Inhumans

The following actors led the eight-episode series as members of the Inhuman Royal Family and their human allies:

  • Anson Mount as Blackagar Boltagon / Black Bolt
  • Serinda Swan as Medusalith Amaquelin / Medusa
  • Iwan Rheon as Maximus Boltagon
  • Ken Leung as Karnak
  • Eme Ikwuakor as Gorgon
  • Isabelle Cornish as Crystalia Amaquelin / Crystal
  • Ellen Woglom as Louise Fisher
  • Sonya Balmores as Auran
  • Mike Moh as Triton

Anson Mount as Black Bolt the Silent King

Anson Mount carries the unique challenge of playing Black Bolt, the King of Attilan. In the Marvel Universe, Black Bolt’s voice is so powerful that even the softest whisper can level a city. This narrative constraint required Mount to deliver a performance entirely without spoken dialogue.

To prepare for the role, Mount rejected the idea of using standard American Sign Language (ASL). He reasoned that since the Inhumans had been isolated on the moon for generations, they would have developed their own unique communication system. Mount created a personal sign language system, documenting it in a file of over 50 pages. His performance relies heavily on facial expressions and specific hand gestures to convey complex leadership decisions and emotional turmoil. This approach added a layer of realism to the character, moving beyond simple mime to a structured, internal logic of communication.

Black Bolt is portrayed as a leader burdened by the weight of his crown. His journey in the series involves being stranded on Earth, specifically in Hawaii, where he must navigate a world he doesn't understand while unable to ask for help verbally. Mount’s portrayal focuses on the stoicism and the hidden vulnerability of a man who can never speak to his loved ones without risking their lives.

Serinda Swan as Queen Medusa

Serinda Swan portrays Medusa, the Queen of the Inhumans and the wife of Black Bolt. Her primary power is her psychokinetic control over her hair, which she can move and use as extra appendages with immense strength.

Swan's role was physically demanding. On set, she often wore a wig weighing approximately four pounds. The production used a combination of practical effects and CGI to bring her prehensile hair to life. Swan described her performance as "acting with an appendage that isn't there," necessitating a deep synchronization with the visual effects team. In the series, Medusa serves as Black Bolt’s voice, interpreting his signs for the court and acting as his most trusted advisor.

A significant turning point for Medusa in the show occurs when her hair is forcibly removed, stripping her of her primary power and status. Swan’s portrayal then shifts from a regal, confident queen to a resilient survivor forced to find her worth beyond her inhuman abilities. This arc explores her tactical intelligence and her fierce devotion to her family.

Iwan Rheon as Maximus the Revolutionary

Iwan Rheon, widely known for playing complex antagonists, takes on the role of Maximus, Black Bolt’s brother. Unlike the rest of the Royal Family, Maximus lost his Inhuman gene during the Terrigenesis process, making him effectively human in a society that prizes genetic superiority.

Rheon’s Maximus is not a stereotypical villain. The character is driven by a desire for social reform and a belief that the Inhuman caste system is inherently unjust. He views himself as a liberator of the lower-caste Inhumans who are forced to work in the mines of Attilan. Rheon brings a charismatic yet manipulative energy to the role, showcasing Maximus’s ability to sway public opinion and lead a military coup against his own brother.

The conflict between Maximus and Black Bolt is the emotional core of the series. Rheon portrays Maximus as a man deeply hurt by his family’s rejection, seeking validation through power. His performance highlights the "human" frailty within the Inhuman society, making him a compelling and often sympathetic antagonist.

Ken Leung as Karnak the Strategist

Ken Leung plays Karnak, Black Bolt’s cousin and closest advisor. Karnak’s unique ability is the capacity to see the "fault" in everything—whether it be a physical structure, a plan, or a person’s character. This makes him the ultimate strategist for the Royal Family.

Leung’s portrayal emphasizes Karnak’s philosophical and often detached nature. Because he sees flaws everywhere, he can be cynical and blunt. The character undergoes a significant transformation when a head injury temporarily impairs his ability to see faults, forcing him to rely on intuition and human emotion for the first time. Leung captures this vulnerability, showing a master strategist struggling to navigate a world that is no longer predictable. His interaction with the human characters on Earth provides a contrast between Inhuman logic and human spontaneity.

Eme Ikwuakor as Gorgon the Guardian

Eme Ikwuakor portrays Gorgon, the leader of Attilan’s Royal Guard and another cousin of Black Bolt. Gorgon’s physical transformation gave him hooves instead of feet, allowing him to create devastating seismic waves by stomping the ground.

Ikwuakor brings a high level of physicality and "warrior spirit" to the role. Gorgon is depicted as the "act first, think later" member of the family, providing a contrast to Karnak’s methodical approach. In the series, Gorgon is fiercely loyal to his soldiers and his king. His arc in Hawaii involves him training a group of human surfers to help him fight Maximus’s forces, showcasing his adaptability and his sense of honor. Ikwuakor’s performance balances the character’s brute strength with a genuine warmth and protective instinct for his family.

Isabelle Cornish as Crystal

Isabelle Cornish plays Crystal, Medusa’s younger sister and the youngest member of the Royal Family. Crystal is an elementalist, capable of manipulating earth, air, fire, and water. She is also the primary companion of the teleporting dog, Lockjaw.

Cornish portrays Crystal as a character in the midst of a coming-of-age journey. Initially seen as somewhat naive and sheltered within the palace walls of Attilan, she is forced to grow up quickly when the coup occurs. Her time on Earth involves learning about human culture and developing a sense of independence. Cornish highlights Crystal's optimism and her burgeoning sense of responsibility as she learns to use her immense powers to protect others.

Ellen Woglom as Louise Fisher

Ellen Woglom plays Louise, a character created specifically for the television series rather than being adapted from the comics. Louise is a human scientist working at a private aerospace company with an obsession for the moon and lunar studies.

Louise serves as the audience’s surrogate, providing a bridge between the mundane world of Earth and the fantastical world of the Inhumans. Woglom portrays her as quirky, highly intelligent, and socially awkward, often missing social cues because of her intense focus on her work. Her partnership with Medusa is one of the show's highlights, as the two women from vastly different backgrounds learn to respect each other's strengths. Louise’s technical knowledge proves vital in helping the Royal Family navigate Earth's technology and track their lost members.

Supporting Cast and Recurring Characters

The series also features several key supporting actors who flesh out the world of Attilan and the conflict on Earth:

Sonya Balmores as Auran

Sonya Balmores plays Auran, the head of the Royal Guard under Maximus’s new regime. Auran is a formidable warrior with a regenerative healing factor, making her nearly impossible to kill. Balmores portrays her as a no-nonsense, lethal operative who is fanatically loyal to Maximus. Her relentless pursuit of the Royal Family on Earth provides much of the show’s physical tension.

Mike Moh as Triton

Mike Moh portrays Triton, Black Bolt’s cousin who possesses fish-like features and the ability to live underwater. Triton is used as a scout and an assassin by the King. Although his screen time is limited, Moh’s performance in the opening sequences establishes the high stakes of the series and the dangers facing the Inhumans.

Henry Ian Cusick as Dr. Evan Declan

Henry Ian Cusick plays Dr. Evan Declan, a human geneticist who becomes entangled with the Inhumans. Declan is interested in the Inhuman DNA for scientific reasons, and his character explores the ethical implications of human-Inhuman interaction. Cusick brings a sense of professional curiosity and moral ambiguity to the role.

The Role of Lockjaw

While not played by a human actor, Lockjaw is a central "member" of the cast. Lockjaw is a 2,000-pound bulldog with the ability to teleport himself and others across vast distances, including between the Earth and the Moon.

The character was created using high-end CGI. The actors on set often had to interact with a large blue foam "stunt dog" to ensure their eye lines and physical movements were correct for the final composite. Lockjaw serves as the primary mode of transportation for the Royal Family and provides moments of levity and heart within the series. His bond with Crystal is portrayed as a deep, loyal friendship.

Casting Dynamics and Production Insights

The casting of Marvel's Inhumans was a collaborative effort led by showrunner Scott Buck and Marvel Television executive Jeph Loeb. The goal was to find actors who could ground the fantastical elements of the characters in real emotion.

Anson Mount was cast relatively late in the process, but his dedication to creating a unique sign language immediately impressed the producers. The chemistry between Mount and Serinda Swan was considered essential, as their relationship had to be conveyed without traditional dialogue. The producers noted that Swan’s ability to communicate Medusa’s internal thoughts through her reactions to Mount’s signs was key to making the Royal Family’s marriage believable.

Iwan Rheon was a high-profile addition to the cast, fresh off his success in other major television dramas. His casting was intended to give Maximus a layer of intellectual depth, ensuring that the character was seen as a political rival rather than just a "bad guy."

What happened to the Inhumans cast after the show?

Following the show's conclusion after one season in 2017, the actors moved on to various other projects. However, the cast remained a topic of interest for Marvel fans, particularly regarding the possibility of their return to the Marvel Cinematic Universe (MCU).

In 2022, Anson Mount made a surprise return as a version of Black Bolt in the film Doctor Strange in the Multiverse of Madness. This appearance, featuring a comic-accurate costume, was seen as a nod to the fans and a recognition of Mount’s dedication to the character, even if the version in the film was from a different reality within the multiverse.

Serinda Swan has continued to lead successful series, including Coroner, while Iwan Rheon has appeared in a variety of international film and television roles. Ken Leung has become a prominent fixture in the industry, notably appearing in Industry and the live-action Avatar: The Last Airbender.

Why was the Inhumans cast's performance unique?

The cast of Marvel's Inhumans faced several unique challenges that are not typically found in standard superhero fare:

  1. Silent Leadership: Anson Mount had to lead the series without speaking, relying on a custom-built sign language.
  2. Physical Effects: Serinda Swan had to act as if her hair was a living, breathing entity, often while wearing a heavy, uncomfortable wig.
  3. CGI Interaction: The entire cast had to frequently interact with an invisible 2,000-pound dog (Lockjaw), requiring high levels of imagination and coordination.
  4. Isolation Themes: The actors had to convey a sense of "otherness," portraying characters who had lived on the moon and were seeing Earth for the first time.
