NEW YORK (CBS) Reports surfaced back in 2010 that actor Mark Ruffalo was added to a government terrorist watch list -- which turned out to be not so accurate.

According to the San Francisco Chronicle, the star of “The Kids Are All Right” and “Zodiac” was placed on a terror advisory list by Pennsylvania’s Office of Homeland Security after helping to promote the documentary “Gasland” and speaking out about his concerns over natural gas drilling.

The report was quickly refuted, though -- by both Ruffalo himself and the Department of Homeland Security.
