Mark Ruffalo was added to the terror advisory list reportedly because he organized screenings for the documentary Gasland that is about natural gas drilling. According to the SF Chronicle, “his efforts to raise awareness and demand a stop to natural gas drilling reportedly attracted the attention of officials from Pennsylvania’s Office of Homeland Security – and he recently discovered it had landed him on a terror alert watchlist.” So how does he feel about it? He reportedly told GQ magazine, “(It’s) pretty f**kin’ funny.”
