In 2008, Ruffalo expressed concern that gas companies were eyeing his family's land in Callicoon, New York. After doing his own investigation, "New York" magazine wrote, he becomes "anti-fracking's first famous face." On October 4, 2010, Ruffalo appeared on "The Rachel Maddow Show" to discuss hydraulic fracturing and the FRAC Act of 2009. He claimed in the December 2010 issue of "GQ" magazine that after he organized screenings in Pennsylvania of a documentary about natural-gas-drilling called "Gasland", he was placed on a terror advisory list. The Pennsylvania Governor's Office of Homeland Security denied the claim.
