When will Season 2 premiere?
Currently, there's no set premiere date nor production information for Season 2. Given that Season 1 only wrapped in October, it seems like the earliest we'll see the second season would be Summer 2020.
Who will return for Season 2?
It's reasonable to expect all of the Gemstones to return for a second season, with series creator Danny McBride back in the center as Jesse Gemstone, the eldest son of the family. That means more of John Goodman as Eli, the patriarch, Adam Devine as Kelvin, the family baby and, therefore, the Gemstones' youth minster, and Edi Patterson as Judy, the middle child, as well. We'll also likely see the return of Tony Cavalero as Keefe Chambers, Kelvin's Satanist project, Tim Baltz as BJ, Judy's fiancee, Cassidy Freeman as Amber, Jesse's wife, Skyler Gisondo as Gideon, Jesse's oldest son, and Dermot Mulroney as rival pastor Reverend Seasons. With Walton Goggin's Uncle Baby Billy revived in the season finale, expect him to have plenty to atone for in the new season. Given the number of flashbacks in the first season, it wouldn't be out of reach to see more of country singer Jennifer Nettles as Aimee-Leigh Gemstone.
We'll also be seeing some new faces in Season 2, although there's no definite casting information as of yet. "We just started writing Season 2, but we're just excited to be able to dig deeper into this world and introduce you to some new characters," McBride told Entertainment Weekly in a Season 1 postmortem.
