Hulk Placed on Terrorist Watch List

Actor Mark Ruffalo has been added to the terror advisory list.

San Francisco Chronicle reports that the Shutter Island and Zodiac actor -- soon to be seen as the Hulk in The Avengers -- was placed on the list earlier this year after promoting and organizing screenings for GasLand, a documentary about natural gas drilling.

Ruffalo's vocal opposition to drilling and his concerns over how it may affect national water supplies reportedly raised the ire of Pennsylvania's Office of Homeland Security enough to place him on the terror watch list.

But the actor is laughing off being labeled a national security threat, telling GQ Magazine, "(It's) pretty (expletive) funny."
