Hap and Leonard will get into more trouble in 2018.
The third season will take inspiration from The Two-Bear Mambo, the third book of author Joe Landsdale's Hap and Leonard series, much like how Seasons 1 and 2 were based on the first two, Savage Season and Mucho Mojo.
"At once darkly funny and socially relevant, there's no other series like the southern-noir, Hap and Leonard, and we couldn't be prouder that it will continue for another season on SundanceTV," SundanceTV general manager Jan Diedrichsen said.
Season 2 had its finale last month. Purefoy and Williams will return as Hap and Leonard, respectively, as will showrunner John Wirth.
