Josh Fox didn't set out to be a documentary filmmaker. And in 2008, when Fox was canvasing for Barack Obama, hydraulic fracturing meant nothing to him. Things changed when Fox’s parents were offered nearly $100,000 to lease their Pennsylvania land for drilling rights. After seeing people light their contaminated well water on fire, Fox made a film called Gasland, which explores the impact of hydraulic fracturing on everyday Americans. It showcased at Sundance in 2010.
