SundanceTV has renewed its swamp-set, six-episode drama TV series "Hap and Leonard" for a second season following its launch in March. Based on Joe R. Lansdale's books, James Purefoy and Michael K. Williams star as two mismatched best friends who take part in a get-rich-quick scheme that quickly goes awry. Jim Mickle and Nick Damici ("Cold in July") penned the series which Mickle directed while Nick Schumaker and Jeremy Platt are executive producing.
