The new series is based on the award-winning novel franchise by Joe Lansdale, also titled "Hap and Leonard", which is described as a Southern set wry thriller centred on an unlikely friendship between a straight white southern man, and a gay African American Vietnam veteran. Together, the 2 best friends wind up in trouble with various criminals as they attempt to solve local crimes. They work for a former police officer turned private investigator. "Leonard" in the title is Leonard Pine, written (based on my research) as a six-foot five, gay, black Vietnam vet, burdened with major anger issues. Further... "He was raised by his uncle who shunned him after learning he was gay. However when his uncle passes away, he leaves his house and all his assets to Leonard. Leonard has zero tolerance for racist or anti-gay slurs. Although Hap dislikes guns, Leonard has no problem carrying or using them. Quick to anger, at times he cannot understand Hap's aversion to violence or killing if necessary, even when provoked. His relationships are also short and tempestuous. Leonard is the much more aggressive of the two and repeatedly burned down a local crack house that used to be his new next door neighbour". One can only assume that his mercurial and explosive nature is as a result of his family not accepting his homosexuality, as well as having to navigate racism and homophobia, and possibly even PTSD, or a combination of them all.
