Mark Ruffalo 'added to terrorism watchlist' over Gasland
Actor reportedly put on US advisory list after organising screenings of documentary criticising natural gas drilling
Ruffalo attracted the attention of Pennsylvania's Office of Homeland Security when he organised screenings for Gasland, which won the special jury prize at this year's Sundance film festival, and said he was concerned about the impact of drilling on water supplies. The actor has addressed the subject in the latest edition of American GQ.
Gasland, directed by Josh Fox, follows the film-maker as he visits communities in Pennsylvania where natural gas has been drilled. Fox decided to document his trip after a natural gas company wrote to him in 2008 offering to lease his family's land in Milanville, Pennsylvania for $100,000 (£64,000).
The documentary attracted attention for a particular scene in which a local man shows that he is able to set his tapwater on fire (see 2.25 of video, above). Others claim they are suffering from numerous health issues due – they believe – to their water having been contaminated.
