Mark Ruffalo is seen walking on the set of his newest movie Thanks for Sharing on Monday in New York (October 3). The film was written by Stuart Blumberg - the writer of last year's surprise hit film The Kids Are All Right, which Ruffalo also starred in.
Ruffalo was one of the many celebrities taking part in the ongoing "Occupy Wall Street" protests in New York and all over the country. On Friday he tweeted:
"Just got home from #Occupywallstreet demonstration in NYC. It was inspiring. So much kindness. So much belief in humanity."
