If you watched Alien: Earth and wondered who played the barefoot billionaire Boy Kavalier, the answer is Samuel Blenkin. He is an English actor who gained prominence as Scorpius Malfoy in the West End production of Harry Potter and the Cursed Child and has since moved between theatre, streaming dramas and big franchises.

This guide covers his age, training, roles, filmography and what’s coming next.

Who Is Samuel Blenkin?

Samuel Blenkin is an English actor and, by his own musical work, a songwriter. He is best known for playing Boy Kavalier in FX’s Alien: Earth, which was released on 12 August 2025. Before that, he built a steady run of credits, including Black Mirror, The Witcher: Blood Origin and Mary & George.

What sets him apart is range. He has played a Shakespearean prince, a young king, a fairy-tale elf and a tech boy-genius, often within the same few years.

Full Name, Age and Date of Birth

IMDb lists his birth date as 1 April 1996. That makes him 30 today. Wikipedia gives only the year, so treat the exact day as reported by IMDb rather than officially confirmed.

Birthplace and Nationality

IMDb says he was born in Cheltenham, Gloucestershire. Wikipedia says he grew up in Tewkesbury, Gloucestershire. Those two facts don’t conflict. He is English, from the same part of the country.

Height

Sources differ slightly. One height database notes that he listed himself as 5'7" at drama college, while his agency currently says 5'8" (172 cm). A safe summary is “around 5 ft 7 to 5 ft 8 in.” 

Education and Acting Training

He trained at the Guildhall School of Music and Drama in London. He is also a member of the National Youth Theatre. 

Samuel Blenkin’s Early Life and Education

Early Background

Public detail here is thin, and that’s worth saying plainly. He grew up in Tewkesbury, Gloucestershire, and has a younger brother. Little else about his childhood appears in reliable sources, so this guide leaves out the rest rather than guess.

Acting Training and Artistic Development

After auditioning for several drama schools, he was accepted to Guildhall at 18. While still a student, he was cast as Scorpius Malfoy in Harry Potter and the Cursed Child, which marked his professional stage debut. He graduated in 2017. Starting work before graduation is unusual, and it gave him a rare head start.

Samuel Blenkin’s Acting Career

Early Acting Roles

His first screen work was in British television. He appeared in Doctors in 2018 and Grantchester in 2019, then moved into bigger productions. If you like tracking rising British actors, our profile of Misia Butler is a useful companion read.

Theatre Career and Harry Potter and the Cursed Child

In 2017 he took over the role of Scorpius Malfoy at the Palace Theatre in London. Eight shows a week in a major West End production is demanding training. It also made his name known to casting directors.

His stage work didn’t stop there. In late 2025, he joined the cast of the world premiere of Christmas Day at the Almeida Theatre, which ran from 9 December 2025 to 8 January 2026.

Breakthrough Television and Film Performances

His screen run took off in 2019 with Peaky Blinders, where he played Adam Parker. Credits in Dracula, The Sandman, The Witcher: Blood Origin and The Continental followed. He then landed Mary & George and, in 2025, Alien: Earth, which gave him his widest audience yet.

Television Shows and Roles

His television work covers crime, fantasy, horror and sci-fi. The most recognisable are Alien: Earth, Mary & George, Black Mirror, The Witcher: Blood Origin and The Sandman, where he played Will Shaxberd, a version of William Shakespeare.

Samuel Blenkin in Alien: Earth

Who Does Samuel Blenkin Play in Alien: Earth?

He plays Boy Kavalier, the young founder and head of Prodigy Corp. Prodigy Corp is led by Boy Kavalier, who has found a way to transfer the consciousness of terminally ill children into synthetic adult bodies. He is a main character in the series.

Understanding His Character, Boy Kavalier

Kavalier is a tech billionaire who acts like a bored child. He lounges on tables, goes barefoot, and gets restless in serious meetings. Blenkin has said he wanted to push the character to extremes while keeping him just below caricature.

The show is also full of Peter Pan references. Kavalier sits at the heart of many of them. That fits the character: a man who never wants to grow up, running a company built on keeping children alive in grown bodies. 

His Role in the Alien Franchise

Alien: Earth brings the Alien universe to television. Blenkin’s character isn’t the monster. He is the human who makes the danger possible, which is a classic Alien theme: corporate greed that treats people as expendable.

The story isn’t over. Season 2 was renewed in November 2025 and is in production in London, with no premiere date yet announced. He is listed among the returning cast.

Samuel Blenkin’s Most Notable Roles

Davis McCardle in Black Mirror

In the Black Mirror episode “Loch Henry,” he plays Davis McCardle. It’s a short part in one of the show’s best-known modern episodes, and it put him inside a major streaming anthology.

Avallac’h in The Witcher: Blood Origin

As Avallac’h, he stepped into fantasy. He appeared in three episodes of the prequel. The role shows he can handle stylised, otherworldly characters, which later helped with Kavalier.

Scorpius Malfoy in Harry Potter and the Cursed Child

This is the role that started everything. Scorpius is a gentle, awkward teenager at the centre of a famous story. Playing him on the West End gave Blenkin both stage discipline and a loyal fan base. For another young British actor whose career began in a well-known franchise, you could read about John Catesby Harington.

Prince Charles in Mary & George

In Mary & George, he played Prince Charles in a miniseries about the life of Mary Villiers. It’s a period drama role about power and court politics. It showed he could carry royal characters as well as modern ones.

Other Notable Performances

Two other credits stand out. In The Sandman, he played a young Shakespeare, a fun piece of casting for a classically trained actor. In 2025 he also took on Hamlet in the Royal Shakespeare Company’s Hamlet Hail to the Thief, a production featuring music from Radiohead’s 2003 album Hail to the Thief. Few actors get that kind of role at 29.

Samuel Blenkin’s Music and Artistic Interests

Musical Influences and Songwriting

Music is a real part of his work, not a hobby line in a bio. He has performed alternative folk songs exploring themes of love, loss, and the apocalypse. Public information about his influences is limited, so it’s best not to name artists without a source.

Recording and Live Performances

A listing from the Green Note venue shows he has played live. Beyond that, there’s little verified detail about studio releases. If you’re searching for his music, check official artist pages and streaming platforms directly.

His Work Across Different Artistic Disciplines

IMDb lists him as an actor, director, and cinematographer. Acting, directing and songwriting all use the same skill: shaping a mood. His Hamlet role makes this clear, since that production blends classic theatre with a rock album. If you enjoy artists who work across fields, our profile of Aliza Barber may interest you.

Samuel Blenkin’s Personal Life

Family and Background

He has a younger brother. Reliable sources don’t name his parents, and this guide won’t repeat unverified claims from low-quality websites.

Relationship Status

As of August 2025, People reported that he was single and focused on his career. That could have changed since, and nothing I found confirms a marriage or engagement.

Conclusion
