Review: Mountainhead (2025)

Mountainhead is an amusing and sometimes insightful comedy of manners about four tech founders getting together at a mountaintop mansion. The comedy of manners is a genre, with origins in the theatre, that satirizes a particular (usually wealthy) social class by exposing the characters’ behaviour and hypocrisy. In Mountainhead, writer-director Jesse Armstrong skewers the powerful tech oligarchs who dominate the 21st-century through the rise and evolution of social media and the growth and expansion of AI.

Steve Carrell plays Randall, whom the others look up to as the eldest and wisest of the group, as he displays a veneer of philosophical, economic, and geopolitical sophistication. Carrell is always great at playing someone who thinks highly of himself. Jason Schwartzman is also well cast as Souper, who feels the weight of not having a net worth over a billion—only in the hundreds of millions, poor him—unlike the other three billionaires. As Souper struggles to make people care about his wellness app, he invites the other three to “Mountainhead” to show off his new mansion under the guise of a poker night reunion. Cory Michael Smith plays Venis (pronounced “Venice”) as a full-on tech bro: he wavers between being totally amped and veiling his depression, as he feels the power and pressures of his global celebrity. For instance, as we meet Venis, he debates launching the latest update of his social media app, Traam, by posting a single word to his millions of followers: the F-word with an extra “u” in it. Not surprisingly, Venis has recently fallen out with the fourth founder, Ramy Youssef’s Jeff. Jeff’s ace in the hole is his AI platform, which all the rest of them want access to. As Venis’ Traam is accused of sparking global conflict through its ability to spread deep fakes and inflame rage, Jeff’s AI might be able to offer a quick censorship fix for the company. As tensions increase between the four characters over the night, we catch glimpses, through TV news and character comments about their social media feeds, that the world outside is descending into chaos.

Armstrong, who wrote the controversial British film satires In the Loop (2009) and Four Lions (2010), is even better known as the TV veteran who wrote The Thick of It (2005-2012) and created the hugely successful Succession (2018–2023). If Succession was often read as a thinly veiled satire of the Murdoch news empire, then Mountainhead similarly teases the audience with parallels to real life that are often unsubtle. It’s hard not to associate Venis and Traam with Elon Musk and X; indeed, the anxious news clips we see in the movie could just as well be clips from real cable news anchors expressing concern about X since Musk’s takeover. Just as unsubtly, a character must comment on “Mountainhead” sounding like Ayn Rand’s The Fountainhead, in case viewers didn’t catch it. Early on, I had concerns that this was going to be a thin, predictable satire of all the usual suspects and all the usual topics.

While the film’s view of the world (and thus its social criticisms) can never really see beyond the purview of The Economist or The Atlantic, the film succeeds nevertheless because of its narrative structure—which is interestingly also the major complaint that has dragged the film’s rating on IMDb to a measly 5.4/10 (as of this review’s publication). I, for one, like the way Armstrong avoids what most movies do. There’s a reason I mentioned the comedy of manners genre from the theatre above: in many ways, this script could be performed as a stage play. Armstrong, for the most part, leans into what can be gained by compressions in terms of both time and location. Most of the film takes place over 24 hours and at the Mountainhead mansion. From what I can recall, most of the music accompanies visual interludes, predominantly at the start of the movie. The running time is dominated by dialogue between the characters, who grow more and more interesting and multidimensional as the film progresses, escaping pure caricature. There’s almost no action, and the conversation is often pseudo-intellectual or philosophical in nature, while interspersed with large helpings of vulgarities and insults. (I say “pseudo” because only one of the four seems to have much knowledge of philosophy, history, and other subjects, while the others, in spite of their jargon and pretensions and engineering savvy, are extremely shallow.) Mountainhead is like having tech bros in a drawing room play, and it works.

That said, at times I thought the dialogue could have been crisper and the plot could have been both tighter and even darker. There’s a meandering quality to the dialogue and plot, as well as an overreliance on handheld camera work, that feels improvised and sometimes sloppy, to the film’s detriment. While events late in the film might shock some, I would argue that Armstrong walks things back a bit too neatly, perhaps while thinking he’s chosen the deeper indictment of greed. Through the character of Randall, the transhumanist motivations underlying much of the tech world are exposed, but the film’s criticisms could have been sharpened and deepened. Just as the film really starts to dig beneath the surface and push the satire to a more outrageous level, it pivots to wrap things up. Why not just cut loose and go for it?

All in all, though, Mountainhead has some good stuff to say. Just as importantly, it is quite enjoyable to watch, if you have some patience and like to observe human behaviour and interactions. As the world becomes ever more digital and inhuman, I welcome more films like this.
