Michael Moore's Latest Target: An 'Immoral' Health Care System

June 13, 2007— -- Polarizing -- that's one way to describe the work of filmmaker and activist Michael Moore, whose new film, "Sicko," takes on the U.S. health care system.

"Nightline's" Terry Moran spent a day with the director in Sacramento, Calif., where Moore teamed with the California Nurses Association to hold a rally at the state capitol.

The nurses wore red "Sicko" T-shirts and cheered for Moore as he criticized America's health care system.

"I am honored to be able to be here today to be able to join with you in a very important movement that is already taking place all across this country," he said. "Because the American people are fed up with this broken health care system. And … it's the nurses who are on the front lines of this war. And it is a war. It's a war against greed."

While the group was walking through the state senate chambers, a group of teenagers recognized Moore and immediately swarmed him, shouting things like 'Oh my God!' and 'I love your work!'"

Moore is known for producing films that inspire love and hate, and stir political debate, but he said in some ways he feels like a failure.

"There's a big part of me that feels like a failure, in the sense that I started out by making a film about General Motors to save my hometown of Flint, Mich., and … Flint today is in far worse shape than when I first made the movie," Moore said.

"I made ["Bowling for Columbine"] in the hopes that there wouldn't be anymore school shootings, and look? We've gone through another tragic school shooting. … 'Fahrenheit 9/11'? Bush was re-elected a few months later. You have to understand that there's a part of me that feels like, geez, when are you going to make a movie that can actually get something done? So I'm hoping that this film, 'Sicko' will do just that."
