Mark Ruffalo on terror advisory list?

Mark Ruffalo has allegedly been placed on the United States terror advisory list.

Ruffalo, who plays the Hulk in the upcoming Avengers movie, was reportedly added to the list after arranging screenings of a documentary about natural gas drilling.

The actor told GQ that his presence on the record was "pretty f**kin' funny".

Ruffalo is an advocate for stopping the practice of natural gas drilling, and organised screenings earlier this year for documentary GasLand, a film that focuses on communities in the United States affected by the practice.
