A 1991 PBS documentary called Dancing Outlaw introduced the world to the life and times of gas-huffing, vengeance-seeking, tap-dancin’ Jesco White. White Lightnin’, which premiered recently at Sundance, is British director Dominic Murphy’s reportedly more surreal take on this fabled Appalachian anti-hero. While not locked in reform school, work camps, or the psych ward, the young Jesco White learned his special breed of clog dancing from his father, who was eventually killed in a random act of hillbilly violence.
