Brian Cox (The Slap), Jeremy Strong (Zero Dark Thirty) and Kieran Culkin (Scott Pilgrim vs The World) are set to star in HBO’s drama pilot Succession. Sarah Snook (Steve Jobs), Nicholas Braun (The Perks of Being a Wallflower) and Matthew Macfadyen (Ripper Street) round out the cast of the project, directed and executive produced by The Big Short’s Adam McKay.

Written by Jesse Armstrong, Succession follows the saga of the Roys, a fictional American global-media family that is not only rich and powerful but also powerfully dysfunctional. The drama will explore family loyalty, international business, and the perils of power in the 21st century. The plot has been drawing parallels to the ongoing real-life saga of the Redstone media clan.

Cox will play Logan Roy, the tough, powerful, and aging patriarch of the Roy family and head of a family-controlled international media conglomerate. Strong will portray Kendall Roy, eldest son from Logan’s second marriage, currently a Division President at the family firm and the heir apparent. Culkin is Roman Roy, Logan’s outspoken, fun-loving son and Kendall’s younger brother. Though still on the board of directors at the firm, he no longer works there. Snook is Shiv (Siobhan) Roy, Logan’s only daughter and younger sister to Kendall and Roman. Like Roman, she sits on the board of directors but does not work at the firm and has been pursuing a career in politics. Braun will play Greg, Logan’s less than competent nephew and a management trainee at one of the firm’s theme parks. Macfadyen is Tom, Shiv’s ambitious partner/fiancé and a senior executive at the firm.

Succession is written/executive produced/showrun by Peep Show co-creator Armstrong and exec produced by Will Ferrell, Frank Rich, Kevin Messick and Ilene S. Landress.
