Alien: Earth on FX is about to change everything we know about the already existing Alien franchise. Set long before the era of Ripley and filled with fresh characters, this prequel brings in new actors, a lot of new technology, and a new kind of terror to our screens at home.
As fans wait for this FX and Hulu release, one question still remains: Who is playing whom in this new Alien futuristic ride?
From mysterious hybrids to soldiers and CEOs, Alien: Earth introduces a new and layered cast. The show drops us into a world where cyborgs, synthetics, and artificial consciousness haze the line between what is human and what is machine.
Leading Alien: Earth is Wendy, a hybrid with a child's mind trapped inside a synthetic body. Each episode delves into her story and her journey, and the people (or beings) around her.
Here's your ultimate cast and character guide to Alien: Earth. Get to know every major role before the premiere.
Alien: Earth cast and character guide - Who plays whom in the upcoming sci-fi horror prequel?
1] Sydney Chandler plays the character of Wendy:
Wendy isn't your average protagonist from Alien: Earth. She is a hybrid, the first of her kind, designed by a corporation chasing the idea of immortality. Wendy's body may be mechanical, but her mind once belonged to a little girl. Now, she leads a group of young hybrids, all part of a military unit, sent on a mission after a spaceship crashes onto Earth.

Chandler captures Wendy's strange blend of innocence and responsibility. She is brave, but also playful, and unsure of her place in a brutal world. Searching for her brother in the chaos, Wendy becomes the heart of Alien: Earth — a character who is caught between being a machine and something more.
You might recognize Sydney Chandler from: Don't Worry Darling, Pistol, and The Golden Rut.
2] Alex Lawther portrays the character of CJ “Hermit”:
CJ, nicknamed Hermit, isn't your typical soldier. He is a medic with a complicated past, especially with Wendy. She may look like an adult android, but inside, she is still his sister.

Their separation years ago shaped who he became. Now, Hermit is part of the recovery mission, navigating the emotional wreckage of reuniting with someone who isn't fully human anymore.
Lawther gives Hermit a raw, emotional core in Alien: Earth. He is not just patching up injuries on the battlefield, but he is also dealing with the ghosts of his past and the haunting reality of what his sister has become.
You might recognize Alex Lawther from: The End of the F ...ing World, Andor, and Departure.
3] Timothy Olyphant plays the character of Kirsh:
Playing against type, Timothy Olyphant takes on Kirsh, a synthetic being whose loyalty is as mysterious as his purpose. Kirsh trains and mentors Wendy, offering guidance while remaining an enigma himself. Is he trustworthy? Or does he serve a deeper corporate agenda?

In the Alien universe, synthetics have always walked a fine line between protector and threat, and Kirsh is no different. Olyphant keeps us guessing every step of the way, making Kirsh one of Alien: Earth's most unpredictable forces.
You might recognize Timothy Olyphant from: The Girl Next Door, Hitman, and Justified.
4] Kit Young portrays the character of Tootles:
Tootles is one of the Lost Boys, a group of young hybrids named after characters from the Peter Pan story. Each was once a sick child, now reborn into powerful android bodies. Tootles, however, doesn't feel like a corporation's creation. He resists the label forced onto him and struggles to keep his identity intact.

Young adds depth and charm to a character who is both confused and aware that he is being manipulated. His journey in Alien: Earth is one of quiet rebellion as an android trying to reclaim his human soul.
You might recognize Kit Young from: Shadow & Bone, Out of Darkness, and The School for Good and Evil.
5] Essie Davis plays the character of Dame Silvia:
Dame Silvia is one of the few fully human characters with real power in Alien: Earth. A top-level scientist in genetics and psychology, she works closely with Boy Kavalier, the young founder of Prodigy Corporation.

Her role in Alien: Earth extends beyond science, as she also serves as a guiding hand for Wendy, helping her understand the harsh truths of humanity. Davis brings a cool intensity to Silvia, a woman navigating the complexities of corporate ambition and personal morality. She might be human, but she is not free from ethical gray areas.
You might recognize Essie Davis from: The Babadook, The History of the Kelly Gang, Nitram, and Babyteeth.
6] Erana James plays the character of Curly:
In Alien: Earth, Curly is the "big sister" among the Lost Boys, and she embraces her new synthetic life with open arms. After being given a second chance through the Phoenix Program, she chooses to focus on the present instead of mourning the past.

Erana James portrays Curly as bold and bright, someone who runs into danger without hesitation. But underneath that courage is gratitude with a survivor who knows how precious this second life really is.
You might recognize Erana James from: We are Dangerous, The Wilds, The Changeover, and Hot Mother.
7] David Rysdahl portrays the character of Arthur:
Arthur is a tech mind working deep inside the Prodigy Corporation in Alien: Earth. He is married to Dame Silvia, and their relationship began through a shared love of science. What started as an idealistic dream quickly becomes morally complicated as Arthur realizes the corporate machine he is now a part of.

David Rysdahl plays Arthur as someone slowly waking up to the consequences of his work. He is a quiet figure in the shadows, but his choices carry massive weight.
You might recognize David Rysdahl from: The Revival, SOULM8TE, Nine Days, and No Exit.
8] Samuel Blenkin plays the character of Boy Kavalier:
Boy Kavalier is the genius founder of the Prodigy Corporation in Alien: Earth. Barely a 20-year-old, he already controls a chunk of the world and wants even more. He is the real-life Peter Pan of the story, who refuses to grow old and stops at nothing to secure a future where his consciousness can live forever.

Samuel Blenkin's portrayal is chilling, and Boy isn't your typical villain, but a symbol of unchecked power. His motivations may be masked as altruistic, but it is clear he is driven by something darker.
You might recognize Samuel Blenkin from: Rhyme or Die, Mary & George, Misbehaviour, The Witcher: Blood Origin, and Mickey 17.
9] Adarsh Gourav plays the character of Slightly:
Slightly, once called Arush, is another hybrid — but his backstory is marked by emotional scars. He sees Wendy as a sister but struggles with jealousy as she has a real connection to her past in CJ, while he feels adrift.
Adarsh Gourav paints Slightly as a deeply layered character, someone who wants to be good but doesn't know how. He holds immense power but wrestles with his own sense of worth, making his arc one of quiet desperation.
You might recognize Adarsh Gourav from: Hostel Daze, Kho Gaye Hum Kahan, Superboys of Malegaon, Leila, and The White Tiger.
10] Diêm Camille portrays the character of Siberian:
In Alien: Earth, Siberian is all human, born into a family with a military legacy. A no-nonsense tactical soldier, she is focused on completing her mission and returning home. Camille gives Siberian a grounded, practical energy.
Siberian is not interested in philosophical questions about hybrids or synthetics, but she just wants to survive. Still, being around creatures and people beyond understanding forces her to question everything she has been trained to believe.
You might recognize Diêm Camille from: Bad Bitch, The Great Silence, Ripple, Baby Pyramid, and Queen of Hearts.
11] Jonathan Ajayi portrays the character of Smee:
Smee is the youngest spirited hybrid, known for his hopeful and upbeat personality. Ajayi describes him as naive, but not because he lacks intelligence. Smee's joy is his strength and maybe his weakness in a world where horror lurks around every corner.

His best friend, Slightly, often acts as his protector, but Smee has his own quiet bravery. His presence reminds us of what innocence looks like in a nightmare.
You might recognize Jonathan Ajayi from: The Drifters, Vigil, and 5lbs of Pressure.
12] Adrian Edmondson plays the character of Atom Eins:
In Alien: Earth, Atom Eins works directly under Boy Kavalier and is as cold as they come. With ties to shady operations and dark corporate secrets, he represents the ruthless face of Prodigy.
Edmondson leans into the sinister aspects of Atom Eins, portraying him as both powerful and completely devoid of empathy. He doesn't just follow orders — he enjoys the chaos they create. Atom Eins is, in every sense, a man without a moral compass.
You might recognize Adrian Edmondson from: The Young Ones, One Of Us, The Comic Strip Presents, and War & Peace.
13] Lily Newmark plays the character of Nibs:
Nibs might be the smallest of the Lost Boys in age, but she carries one of the heaviest emotional loads in Alien: Earth. She is too young to completely understand what she has become and often feels out of place.

Newmark brings a fragile depth to Nibs, a character who is still processing her transformation. She clings to Wendy and Curly for comfort, but the existential weight of her new body never quite leaves her. Her innocence is heartbreaking, especially in a world where survival demands maturity.
You might recognize Lily Newmark from: Welcome to Mercy, Cursed, A Brixton Tale, and How to Fake a War.
14] Babou Ceesay portrays the character of Morrow:
Morrow, a cyborg aligned with Yutani, is one of Alien: Earth's more mysterious figures. Not fully machine but not fully human either, he is described as outdated technology still trying to stay useful in a world that has moved on.
Ceesay's performance blends quiet resilience with inner turmoil. He was saved from the streets as a child, but that salvation came at a cost-one that still defines his choices.
You might recognize Babou Ceesay from: Wolfe, We Hunt Together, and Free Fire.
15] Moe Bar-El plays the character of Rashidi:
Rashidi leads the mission after the alien vessel crash-lands on Earth. A commanding presence, he guides his team through a mission that quickly spirals into the unknown.
With Alien: Earth, Bar-El gives Rashidi both authority and humility, portraying a man doing his best to stay alive while making impossible decisions. What starts as a routine operation turns into a fight for survival against living beings no one was prepared to face.
You might recognize Moe Bar-El from Honour, Femme, and The Bereau.
With Alien: Earth, FX dives deep into untold corners of the franchise's lore and delivers a fresh cast with unique backstories and motivations.
