Grant: A Journey Through Cinema, Theatre, and Eccentricity
From the cult corridors of 1980s British cinema to the expansive universes of Marvel and Star Wars, Grant has carved a unique niche in the performing arts. Known for a distinct vocal quality and a penchant for the idiosyncratic, his career spans decades and mediums, blending high-brow theatre with blockbuster Hollywood productions.
Grant's artistic roots began in Cape Town as a member of the Space Theatre Company. After relocating to London in 1982, he noticed a stark contrast between his upbringing in Swaziland—where he spoke a "period English sound" reminiscent of the 1950s—and the contemporary speech of England. This unique linguistic background was noted by director Charles Sturridge, who observed that Grant spoke as if he were from a previous era.

During the filming of L.A. Story, Grant developed a unique correspondence with co-star Steve Martin via fax. Martin described Grant's writing as a "stream-of-consciousness faucet," praising the raw, unedited, and acidic nature of the messages.

Award-Winning Shorts and Early Successes
In 1995, Grant starred in Peter Capaldi's short film Franz Kafka's It's a Wonderful Life, which earned the Academy Award for Best Live Action Short Film. He continued to explore diverse roles, including Sir Andrew Aguecheek in Twelfth Night (1996) and a musical collaboration with Orpheus in 1997.
Doctor Who and Genre Work
Grant has a complex history with the Doctor Who franchise. He has portrayed the Doctor twice outside the main continuity: as the "Quite Handsome Doctor" in the sketch The Curse of Fatal Death and as the Ninth Doctor in the animated webcast Scream of the Shalka. His likeness also appeared as a projection in the 2024 episode "Rogue."
His first official appearance in the main series occurred in the 2012 Christmas special, "The Snowmen," where he played the villain Walter Simeon. He later reprised this role in "The Bells of Saint John" and "The Name of the Doctor."

Theatre and Musical Ventures
Beyond the screen, Grant is a seasoned stage performer. He made his musical theatre debut with Opera Australia as Henry Higgins in My Fair Lady at the Theatre Royal, Sydney, a role he later brought to the Lyric Opera of Chicago in 2017. He also appeared in Yasmina Reza's God of Carnage, touring several cities including Bath and Brighton.
His versatility extended to radio, where he played intelligence analyst Brian Jones in The Iraq Dossier (2013), a drama focusing on the inaccuracies of the September Dossier regarding Iraq's Weapons of Mass Destruction.
Recent Career Highlights
In recent years, Grant has transitioned into high-profile television and film. He joined the cast of Game of Thrones in Season 6 as Izembaro and played the corporate scientist Zander Rice in Logan (2017). His performance as Jack Hock in Can You Ever Forgive Me? (2018) was a critical triumph, earning him a New York Film Critics Circle Award and multiple major award nominations.

More recently, he appeared in Star Wars: The Rise of Skywalker and portrayed the variant Classic Loki in the Disney+ series Loki. He also appeared in the 2022 Netflix adaptation of Persuasion and the 2023 thriller Saltburn. Looking ahead, he is scheduled to appear in the second series of The Celebrity Traitors in autumn 2026.
The Making of Wah-Wah
Grant stepped behind the camera to write and direct Wah-Wah (2005), a film loosely based on his childhood. The project took over seven years to complete and featured a prestigious cast including Nicholas Hoult and Julie Walters. Grant documented the experience in The Wah-Wah Diaries.
The production was marred by a volatile relationship with producer Marie-Castille Mention-Schaar. Grant described her as a "control freak out of control," citing failures in obtaining song rights and filming clearances in Swaziland. The latter issue eventually required Grant to seek clemency from the King of Eswatini to proceed.
