The highly anticipated HBO original movie Mountainhead, created by Jesse Armstrong, the mastermind behind Succession, premiered on May 31, 2025, and quickly made waves across the entertainment world. Known for his sharp wit and cutting commentary, Armstrong’s latest film continues his exploration of power dynamics, moral ambiguity, and the impact of technology on society. Mountainhead is a dark satire that holds a mirror to our increasingly tech-driven world, blending humor with stark social commentary.
Plot Summary: A Tale of Friendship, Betrayal, and Generative AI
Mountainhead follows the story of four wealthy, influential friends—collectively known as the “Brewsters”—who gather for a weekend retreat amidst the backdrop of a fractured world. The film is set against the backdrop of rising political unrest, social media manipulation, and the perils of generative AI, which plays a central role in the plot.
The central character, Venis Brewster, is a tech mogul and CEO of a social media platform that has come under fire for the spread of AI-generated fake images and deepfakes that have stirred political chaos. As the Brewsters head to a secluded mansion in the mountains to escape the growing tensions outside, they find themselves caught up in a web of deception, power struggles, and personal vendettas.
As Venis grapples with the fallout from his company’s actions, he embarks on a journey to confront his former partner, Jeff, an AI developer who has created a groundbreaking software capable of detecting and verifying real images from fake ones. As the stakes grow higher, the Brewsters begin to question their values, relationships, and the very technology they helped create.
A Contemporary Social Commentary
One of the central themes of Mountainhead is the role of technology in shaping reality and manipulating truth. Armstrong, who is no stranger to exploring the intersection of power and influence, uses this film as a commentary on the dangers of a society that relies on artificial intelligence for validation, entertainment, and even political engagement.
At the heart of the story is the tension between reality and perception—questions that have become increasingly relevant in today’s world, where deepfakes and AI-generated content are reshaping the way we consume information. As the Brewsters confront their own involvement in the propagation of fake news, the audience is forced to reckon with the consequences of a digital society that has blurred the lines between what’s real and what’s fabricated.
The Cast: A Stellar Ensemble
Mountainhead boasts an impressive ensemble cast that includes Steve Carell, Jason Schwartzman, Cory Michael Smith, and Ramy Youssef. Each actor brings a unique perspective to their role, adding depth and nuance to the film’s exploration of privilege, guilt, and moral responsibility.
Carell plays Venis Brewster, the morally conflicted tech mogul who is trying to reconcile his actions with the reality of their consequences. Schwartzman plays Lenny Brewster, Venis’s childhood friend turned bitter rival, who has his own ulterior motives throughout the story. Smith and Youssef play key supporting characters who are involved in the brewing tensions among the Brewsters.
The film’s casting choices elevate the script, adding layers of complexity to characters who may initially appear to be caricatures of wealth and privilege but ultimately reveal their vulnerabilities and contradictions.
Production and Direction: A Masterpiece of Dark Humor
Armstrong’s direction is sharp and incisive, maintaining the same dark humor that made Succession a hit while diving deeper into the moral implications of living in a world dominated by technology. The film’s pacing is deliberately slow, building tension as the characters’ secrets unravel over the course of the weekend.
The cinematography, led by Bradford Young, captures the isolated beauty of the mansion and its surrounding mountains, further underscoring the characters’ emotional isolation. The use of shadows and wide shots enhances the eerie atmosphere, creating a sense of dread and claustrophobia that mirrors the characters’ psychological unraveling.
Reception and Criticism
Mountainhead has received generally positive reviews from critics, many of whom have praised the film’s timely and prescient commentary on the dangers of technology. The satirical nature of the film has resonated with viewers, especially in an age where the ethical implications of AI and social media are hotly debated.
However, some critics have pointed out that the film’s pacing could be a challenge for audiences used to more fast-paced narratives. Despite this, the film’s intellectual depth and biting humor have made it a standout in 2025’s slate of original programming.
Conclusion: A Timely and Thought-Provoking Masterpiece
In Mountainhead, Jesse Armstrong has created a film that is both a gripping social commentary and a darkly comedic exploration of the power dynamics that shape our world. Through its portrayal of wealthy elites caught in a web of technology, betrayal, and guilt, the film forces viewers to question the influence of artificial intelligence on our perception of reality.
Available for streaming on HBO Max and airing on HBO on May 31, Mountainhead is an essential watch for anyone interested in exploring the moral implications of the digital age.
