“Mountainhead” Trailer Reveals “Succession” Creator Jesse Armstrong’s Film Debut

By The Credits | May 16, 2025

There’s no shortage of rich people acting terribly in the actual world, but for those of you who deeply miss the vile, venal shenanigans of Succession‘s Roy family—and we count ourselves among your number—the arrival of Mountainhead is going to do wonders for your soul.

Succession creator Jesse Armstrong is back with this new feature film, which finds four billionaire friends reuniting in a palatial mountain retreat to kick back and enjoy the orchards (upon orchards) of their “labor.” Yet their mountaintop idyll is ruined by a pesky little problem having to do with one of their creations, a generative artificial intelligence, that starts sewing havoc and chaos throughout the world.

Our four billionaires are Randall (Steve Carell), Hugo (Jason Schwartzman), Jeff (Ramy Youssef), and Venis (Cory Michael Smith), the latter of whom is the creator of the AI that’s turning the world into a nightmarescape. The foursome need to deal (or deny) any culpability in the horrors happening the world over, and like any billionaire worth his yacht, they start to believe that the four of them have the power to set everything right. One way to do this is to potentially buy entire countries. Hijinx, acrimony, and bro-tastically bad behavior ensue.

Mountainhead is Armstrong’s feature film directing debut. After his Emmy-laden run on Succession, there’s a lot of excitement around this latest look at the foibles of the grotesquely rich. The film also stars Hadley Robinson, Andy Daly, Ali Kinkade, Daniel Oreskes, David Thompson, Amie MacKenzie, and Ava Kostia

Check out the trailer below. Mountainhead arrives on HBO Max on May 31.
