Actor Mark Ruffalo on terror watch list

Actor Mark Ruffalo, 43, has been placed on a terror watch list by U.S. officials after supporting a new documentary about natural gas drilling.

“The Kids Are All Right” star spoke out about the dangers to the national water supplies when arranging showings for “GasLand,” which was opposed by the natural gas industry, this year.

Those activities got the attention of officials from Pennsylvania’s Office of Homeland Security, which eventually led him to be placed on a terror alert watch list.

However, Ruffalo told a US magazine that he was not worried about being seen as a security threat. And, in the interview with GQ magazine, he said, “(It’s) pretty fucking funny.”
