Ahead of the film’s HBO premiere on May 31st 2025, which translates to a June 1st landing on Sky, there’s a new trailer for Mountainhead.

Written and directed by Succession’s Jesse Armstrong, it gives us another look a the show’s four tech billionaires. Together, they indulge in some juvenile bro behaviour before chaos hits in the real world.

We also now have a tag line for the movie too: Humanity is in their hands.

The supporting cast includes Hadley Robinson as Hester, Andy Daly as Casper, Ali Kinkade as Berry, Daniel Oreskes as Dr. Phipps, David Thompson as Leo, Amie MacKenzie as Janine, and Ava Kostia as Paula.

Updated 23/04/25: The surprise project from the Succession director lands at the end of May.

Mountainhead bottles four tech bros in a remote location while an international crisis develops in the real world.

Even in the short teaser trailer, we can see that the film is rife with the banter that made Succession so watchable. It also delivers some pointed satire on social media and its potential to stoke tensions…

Mountainhead lands on HBO and Max in the US on May 31st 2025. In the UK, it’s on Sky and streaming service NOW on 1st June.
