Viewers will get an early look at Mountainhead, Jesse Armstrong's follow-up project to his hit series Succession.

The speed of the production pretty well matched the public timeline, Armstrong said. He pitched the idea to HBO chief Casey Bloys in December 2024, then wrote the script in January. Most of the cast signed on before Armstrong finished the script, and the production time was short.

If you miss spending Sunday nights with the Roy family, then you definitely want to watch Mountainhead, the new HBO original movie from Succession creator Jesse Armstrong that premieres this weekend.
