Based on the book series by Joe R. Lansdale, the drama follows two lifelong best friends, Hap Collins (James Purefoy), an East Texas white guy with a weakness for Southern women, and Leonard Pine (Michael K. Williams), a gay, black Vietnam vet with a hot temper.
The third season will be an adaptation of the novel The Two-Bear Mambo.
Jim Mickie and Nick Damici developed the series. John Wirth serves as showrunner. AMC Studios produce.
"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," said Jan Diedrichsen, General Manager, Sundance TV. "James and Michael bring new depth and dimension to the buddy-action genre, and Joe Lansdale's brilliant work continues to be in excellent hands with John Wirth and company."
