Lauren Tsai is “Switch,” a young mutant whose secret ability serves as the key to executing David Haller’s plan.

Career Highlights

Raised in Hawaii, Lauren Tsai is an actress, model and artist. She starred in the hit Japanese reality series Terrace House: Aloha State, and stars in Noah Hawley’s critically-acclaimed FX series Legion as “Switch.” As an artist, Tsai most recently collaborated with Marc Jacobs on a capsule collection that was released in October 2018.

Dan Stevens stars as “David Haller.” His whole life, David believed he was schizophrenic and struggled to maintain his sanity. All that changed when he met the girl of his dreams. With her help, David realized that he is a powerful mutant. He managed to win an epic battle for control of his mind, only to realize that the root of his problems lay much deeper. Now, David finds himself violently at odds with those he once called friends. In order to truly repair the damage he has wrought, he must journey further into the recesses of himself than ever before.

Rachel Keller stars as “Sydney ‘Syd’ Barrett.” Self-sufficient and street smart, Syd used her pointed demeanor to keep people at a distance until she fell in love with David, a powerful mutant. They had a romance for the ages, until, that is, Syd was betrayed by the man she trusted most. Now devoted to herself above all others, Syd recognizes that her ex was never the hero of this story. She is.

Aubrey Plaza portrays David’s friend “Lenny Busker.” Despite a life of drugs and alcohol abuse, David’s friend Lenny knows that any day now her life is going to turn around, which gives her the likable energy of the impossible optimist. In her newfound position as David’s right hand man, Lenny is pulled between her pursuit of personal happiness and the execution of David’s plans.

Bill Irwin plays the brilliant geneticist “Cary Loudermilk,” who is Kerry’s counterweight; a scalpel to her hammer. Quiet and reserved, he’s often mistaken as shy. But once you get to know him, Cary is a slyly funny, thoughtful, brave man who’d fall on his sword for those he loves, especially his closest friend, Kerry.

Navid Negahban portrays “Amahl Farouk,” the villain with a thousand faces, aka the Shadow King. He is an ancient mutant who resided in David’s mind for 30 years. He is a trickster with a wicked sense of humor who delights in using his mental influence to turn the world upside down for those around him. Now that Farouk’s aligned with the noble forces of Division 3, however, surely his evil ways have come to an end…

Jeremie Harris stars as “Ptonomy Wallace,” a pragmatist with a dry sense of humor who is the kind of leader you’d follow out of your foxhole. However, his photographic memory, coupled with the ability to read the memories of others, means his gift is also a burden. This burden has only increased upon the upload of Ptonomy’s consciousness into Division 3’s computer system. His abilities have been magnified tremendously, but has that come at the cost of his humanity?

Amber Midthunder stars as “Kerry Loudermilk,” a mover and doer who is the kind of person that’s never satisfied with a green pasture. There’s nothing she loves more than a good fight… except maybe Cary, the one person with whom she is truly close.

Hamish Linklater is “Clark DeBussy,” an interrogator from the government’s covert group, Division 3. Sent to study David’s powers, Clark unexpectedly became embroiled in the battle against the Shadow King. Now, Clark faces an opponent far more dangerous than any encountered previously: David Haller.
