Four super-rich tech leaders gather for a poker weekend in a mountain mansion while AI technology leads to global chaos in the new HBO film from Succession creator Jesse Armstrong.

Following his HBO series Succession, Jesse Armstrong's latest project, Mountainhead, is a film about four tech billionaires whose mountain retreat is disrupted by a global catastrophe.

The Netflix series is Tina Fey's touching tribute and knowing update to a 1981 Alan Alda movie — a smart, nuanced take on marriage, friendships and the way changing circumstances can affect them both.
