Appearing on Tuesday night's Countdown with Keith Olbermann, actor Mark Ruffalo cheered on protesters at "Occupy Wall Street," calling his visit to the protest site "a beautiful celebration of democracy."


"This is a movement that's transcending political ideologies," he said. "It's a movement that's touching people all over the United States. And, like all great democratic movements, it takes time for foment. You come forth with your grievances first. It takes time. In a true democracy, you don't just hand the democracy over to a leader. We happen to live in a time where we can have a leaderless revolution, where people's voices from disparate parts of the world, disparate parts of the country, are able to speak out."
