Barry Levinson knows the beast that is mass media.
The director explored the impact of television on family life with his 1990 drama "Avalon," and he revealed the ways politicians use the news to manipulate the public in his clever satire "Wag the Dog." Now he's turned the camera on himself and his peers with a film essay entitled "Poliwood" about celebrity activism.
"It's mixed emotions," he said. "You have to worry about how the media has played such a hand in the political process. I think that's a great worry. On the other hand, there are millions of people who are enthusiastic about change."
