But the draw on the night CBS News chief political correspondent Jeff Greenfield was there, the night's premiere wasn't isn't "Pirates of the Caribbean" or Spiderman, but this man: filmmaker Michael Moore, whose new film "Sicko" assails America's health care system and champions a government-run health care system.
"We can no longer have a health care system where private health insurance is calling the shots-we have to remove the profit."
"Sicko" features affecting stories of personal suffering at the hands of indifferent corporations, and then celebrates the government run systems of Canada, France, and Britain. Most controversially, Moore took 9/ll rescue workers denied health care after taking ill to Guantanamo Bay, to demand the same care given al Qaeda suspects.
Later, in a Havana hospital, they received health care that Moore claimed was typical an assertion likely to be sharply challenged.
But beyond the controversies that seem to surround every Moore film is it accurate advocacy? Is it distorted propaganda lies a bigger question. Could it help shape the direction, even the outcome, of the coming Presidential campaign? History says there's reason to be skeptical.
"I want people to go see this movie and come out and say, we have to do something," Moore said.
There are examples of cultural events that helped shaped politics.
In 1979, "The China Syndrome," released just after the nuclear accident at Three Mile Island, which intensified anti-nuclear sentiment.
But in more recent years, 1983's "The Right Stuff" did nothing to advance the Presidential hopes of former astronaut John Glenn, and Moore himself says his 2004 smash, "Fahrenheit 9/11" didn't change many minds about President Bush
"Probably a lot of people who went to see it already didn't like what was going on," Moore said.
And so far, the candidates for president have talked a lot about changing the system, but no one has come close to advocating the kind of government run national health-care system Michael Moore proposes.
Why not? Health analyst Paul Ginsburg says Americans are just different.
"We're much less willing to have government make decisions for people than is the case in Canada and Europe. It's a cultural difference," Ginsburg said.
"We grew up with this attitude of everyman for himself," Moore said. "It's not going to serve us well in the 21st century."
Moore has proven he can draw much bigger audiences than the typical documentary. But if history is any guide, "Sicko" is likely to have a lot more impact at the box office than at the ballot box.
