The Audacity Full Cast Guide: All Actors & Their Characters So Far, Explained

Credit: AMC+

Set in Silicon Valley, The Audacity starts with a company already in trouble and then makes it worse. Hypergnosis is falling apart after its value gets manipulated, and Billy Magnussen‘s Duncan Park is trying to hold it together without really fixing anything. The fallout hits everyone around him, from JoAnne Felder exploiting client secrets to others dealing with decisions they didn’t make.

With Episodes 1 and 2 out on April 12, 2026, and Episode 3 next, the 8-episode season is already renewed for Season 2, as confirmed by AMC on its official Instagram. The cast is spread across familiar TV actors and newer faces in different parts of the story. Here’s a complete breakdown of the actors and their roles so far.

TV Show:	The Audacity
Creator:	Jonathan Glatzer
Episodes:	8 (Season 1)
Network:	AMC

Billy Magnussen as Duncan Park

Magnussen, coming off roles in Made for Love and Black Mirror, leads the show as Duncan Park, CEO of Hypergnosis, a data-mining company hemorrhaging credibility. Duncan kicks off the series in crisis: he leaked a fake acquisition rumor to spike Hypergnosis stock, Cupertino pulled out, and now his valuation is built on nothing.

The show calls him a “dumb man’s genius,” someone desperate to prove he belongs, willing to do anything to win. By the end of Episode 1, he blackmails his own therapist into becoming his inside source. Magnussen plays him as someone who still doesn’t see himself as powerful, which, per the actor, is exactly what makes Duncan dangerous (via The Wrap).

Sarah Goldberg as JoAnne Felder

Sarah Goldberg is JoAnne Felder, a performance psychologist to Silicon Valley’s elite who privately trades stocks on her clients’ confidential information. She’s mired in student debt, married to her former professor, and fueling jealousy behind a therapist’s poker face.

Goldberg, known for playing morally blind women in HBO’s Barry, plays her without a shred of sympathy-fishing, which avoids softening her moral contradictions.

Rob Corddry as Tom Ruffage

Rob Corddry takes a clear turn away from his usual comedy roles as Tom Ruffage. Tom is a gay, alcoholic Desert Storm vet and VA undersecretary who comes to Silicon Valley looking for a tech contractor to modernize the agency’s files. He’s heading in to do genuine good, which isn’t something Silicon Valley tends to respond to.

Corddry plays him as both fragile and principled, and that tension makes Tom feel like the show’s closest thing to a conscience, though in this world, that bar is low.

Meaghan Rath as Anushka Bhattachera-Phister

Meaghan Rath, who started out in comedy (Being Human), has Goan Indian roots and knew she wanted to act early enough to ask for an agent as a kid. Here, she plays Anushka Bhattachera-Phister, the Hypergnosis’ Chief Ethicist, a title that sounds important until you watch it do absolutely nothing.

Her input is ignored even in high-stakes decisions, and despite sitting on the board, she rarely drives outcomes. She’s also directly entangled through her history with Duncan and her marriage to Martin Phister, which keeps her close to power.

Simon Helberg as Martin Phister

Simon Helberg, widely recognized from The Big Bang Theory, plays against that high-energy persona here. As Martin Phister, the founder of Hypergnosis and Anushka’s husband, he should be the one setting direction, but he isn’t. So far, Martin feels like he’s working at a different pace than the company he built.

Helberg keeps the performance restrained. A trained pianist who performed live in Florence Foster Jenkins, he brings that same precision here, making Martin’s lack of urgency stand out more than if it were played louder.

Paul Adelstein as Dr. Gary Felder

Paul Adelstein steps into the role of Dr. Gary Felder, JoAnne’s husband and former professor. Their dynamic is already messy. He taught her, and that hierarchy hasn’t fully disappeared. Even now, he speaks with that same authority, which makes their relationship feel less like equals and more like an extension of that past. And right now, Gary feels like he hasn’t stopped being her professor.

Adelstein has built a career around authority figures, from medical dramas like Private Practice to more controlled, procedural roles like Leo Bergen (Scandal). He leans into that here, which makes Gary’s presence feel dominant.

Lucy Punch as Lili Park-Hoffsteader

Lucy Punch plays Lili Park-Hoffsteader, Duncan’s wife, and notably, she’s one of the few people in his life who isn’t impressed by his world. While everything around Hypergnosis runs on perception and positioning, Lili questions, pushes back, and doesn’t seem interested in maintaining the image Duncan is trying to control. For now, Lili feels less like part of his life and more like a disruption to it.

Punch is usually cast to heighten scenes, bringing loud, chaotic, slightly unhinged energy in roles like Bad Teacher. Here, she does the opposite. She keeps Lili grounded and direct, which makes her stand out more in a space where everyone else is putting on some version of an act.

Other Supporting & Recurring Cast

Everett Blunck as Orson Stern

Everett Blunck comes in with serious indie credibility, earning Critics Choice nominations for The Plague (via IMDb). Here, he plays Orson Stern, JoAnne’s 15-year-old son, who’s been uprooted from Baltimore while his father deals with cancer and is now left mostly on his own. He’s not part of Hypergnosis or Silicon Valley’s power games. But in Episode 2, he finds a hidden room in their house that lets him overhear JoAnne’s therapy sessions.

Thailey Roberge as Tess Phister

Thailey Roberge (Reginald the Vampire) plays Tess Phister, and she’s basically the irony of Martin’s entire life. She’s repeating the 11th grade, in court-ordered therapy, and casually stealing. Orson catches her taking one of Duncan’s tungsten cubes in Episode 1. Her father is building tech to help isolated teenagers, while she’s clearly one of them.

Ava Marie Telek as Jamison Park-Hoffsteader

Ava Marie Telek (Freaks) plays Jamison Park-Hoffsteader, Duncan and Lili’s daughter, and she’s already under pressure from every direction. She’s being pushed toward Stanford, discussed like a project, even treated by Gary as part of a plan rather than a person. At home, Lili keeps a close watch on her body, which adds another layer of control. She appears across 6 of the show’s 8 episodes, placing Jamison consistently within the story rather than on the sidelines.

Zach Galifianakis as Carl Bardolph

Zach Galifianakis (Between Two Ferns) plays Carl Bardolph, one of JoAnne’s clients, a Silicon Valley figure who’s clearly made money but can’t get past how little appreciation he gets for it. In Episode 1, he spirals in therapy about how people resent people like him, insisting they “built everything” others rely on.

Randall Park as Gabe

Randall Park (WandaVision) plays Gabe, Duncan’s former business partner, who lives in isolation on a heavily guarded private island. He’s out of Hypergnosis and completely removed himself from it, which suggests whatever he knows made him step back entirely.

Jess McLeod as Harper

Jess McLeod plays Harper, one of the younger characters positioned around the Hypergnosis world but not actually inside it. She’s connected through the same teen circle as Orson and Tess, which places her close to the fallout rather than the decisions themselves. Harper feels like someone experiencing the consequences of this world without having any control over it.

Rukiya Bernard as Beatrice Webb

Rukiya Bernard (Van Helsing) appears in a recurring role as Beatrice Webb. Beatrice Webb is a Hypergnosis-affiliated executive, present in internal discussions but not among the core decision-makers. Her screen time so far is limited, appearing briefly across early episodes.

Andrew Bushell as Jeffrey Carter

Andrew Bushell plays Jeffrey Carter, who works alongside Tom Ruffage on the government side, involved in bringing Hypergnosis in to help modernize VA systems. So far, Jeffrey feels like part of the government machinery, trying to work with tech, rather than someone shaping the deal himself.
