15 Actors Perfect for the Role of Martian Manhunter in the DCU
J’onn J’onzz has been a Justice League cornerstone since the Silver Age, with powers that span telepathy, shapeshifting, flight, invisibility, and an encyclopedic mind for strategy. He carries a quiet authority in the comics and animation, often serving as the League’s connective tissue during crises while navigating the grief of a survivor of Mars. Live action and animation have already shown how much range the character allows, from undercover detective stories to cosmic diplomacy and big team battles.
Fans routinely bring up Martian Manhunter when they talk about DCU world building because the character threads together street level heroes, global agencies, and off world threats. Past portrayals include David Harewood in ‘Supergirl’ and Harry Lennix in ‘Zack Snyder’s Justice League’, with the animated voice most associated with the role coming from Carl Lumbly across ‘Justice League’ and ‘Justice League Unlimited’. With the DCU expanding, here are actors frequently discussed in fan communities whose resumes line up with the character’s blend of presence, voice, and genre experience.
Chiwetel Ejiofor
Chiwetel Ejiofor has led prestige dramas and major franchises, with credits across ‘12 Years a Slave’, ‘Doctor Strange’, and ‘The Old Guard’. He has extensive voice and performance work that includes Scar in ‘The Lion King’, which demonstrates precise control over cadence and tone in studio environments that mirror ADR and performance capture workflows.
He trained at the National Youth Theatre and has Royal National Theatre experience, which means years of text heavy performance and dialect work. He also has a record of playing characters who operate within complex moral frameworks and covert organizations in projects like ‘Serenity’ and ‘Secret Invasion’, a background that maps cleanly onto undercover and tactician aspects of J’onn J’onzz.
Sterling K. Brown
Sterling K. Brown’s television run on ‘This Is Us’ earned multiple Emmys, and his film work ranges from ‘Black Panther’ to ‘American Fiction’. He is accustomed to ensemble storytelling where character relationships drive the plot, a common setup for Justice League stories built around mission rooms and cross team coordination.
His stage and voice credits include ‘Frozen II’ and documentary narration, which shows facility with vocal performance beyond on camera acting. Brown’s schedule has balanced film and limited series commitments in recent years, a production pattern that fits recurring appearances across multiple DCU projects.
Chukwudi Iwuji
Chukwudi Iwuji is a Royal Shakespeare Company alumnus who brought a heightened villain to life as the High Evolutionary in ‘Guardians of the Galaxy Vol. 3’. His television work on ‘Peacemaker’ shows familiarity with DC sets and VFX heavy production, where eyelines, plate shots, and stunt unit handoffs are routine.
He has led classic stage roles that demand precise articulation and breath control, which translates well to ADR sessions and performance capture pickup days. Iwuji also has experience with emotionally intense material in limited series drama, which supports the backstory beats tied to the loss of Mars in Martian Manhunter storytelling.
David Harewood
David Harewood portrayed J’onn J’onzz on ‘Supergirl’, handling both the heroic identity and a human cover while working with prosthetics, voice processing, and full body VFX. That run included crossover episodes with multi camera coordination across Arrowverse shows, a useful background for big DCU crossovers.
Beyond DC, Harewood’s credits in ‘Homeland’ and ‘The Night Manager’ cover intelligence operations and interagency politics. That experience gives him a track record with command scenes, briefings, and calm crisis management that often define Martian Manhunter in team settings.

Lumbly’s decades of voice work demonstrate consistency in booth technique, which suits performance capture and vocal layering often used for alien characters.

His voice acting credits include multiple DC animated projects, along with roles in ‘Justice League: Doom’ and ‘Young Justice’. Morris brings familiarity with the studio’s character bible approach to continuity and with sessions that require separate recording across different cities, a common logistics pattern in franchise production.
