The season 4 premiere of The Righteous Gemstones is set in 1862 and stars Bradley Cooper. Here is how it happened & when the regular cast will return.

The fourth and final season of "The Righteous Gemstones" has finally arrived on HBO. With the final season comes new responsibility for the Gemstone kids. They finally have what they want – control of the family megachurch - but leadership turns out to be a lot more difficult than any of them expected.

A new season of “The Righteous Gemstones” will premiere on Sunday, March 9.

Prelude, plays like a Civil War movie. Graphic, violent, touching, and a tiny bit sadistic. Bradley Cooper plays a Gemstone ancestor and he carries the Episode. His scheming, unscrupulous crook who lives for the money goes from belonging to the trash of humanity to finding his idea of honor and redemption.

The Righteous Gemstones” is funny, wry, clever, disgusting, moving, shocking, and endearing in ways that are purely aspirational for most comedies on TV, and I’m sorry to say goodbye to it.

Cassidy Freeman, Tim Baltz, and Tony Cavalero co-star as the Gemstone siblings’ respective partners, Amber, B.J., and Keefe. Skylar Gisondo will also return as Jesse and Amber’s oldest son, Gideon. These HBO Sundays are also set to be a Goggins double feature, as the actor portrays fan-favorite character Baby Billy Freeman, Eli’s brother-in-law.

After The Righteous Gemstones' thrilling season 4 premiere set during the Civil War, I'm convinced Danny McBride should make a western for HBO.
