CANNES, France (AP) -- Filmmaker Michael Moore says his latest documentary was meant to be quieter and more reflective.
But it's not working out that way -- at least not the reaction.
Moore's film about the American health care system, called "Sicko," got loud applause after its first screening at the Cannes Film Festival.
One critic thinks it could have even more impact that his previous efforts, "Bowling For Columbine" and "Fahrenheit 9/11."
The U-S government has already taken notice. It's investigating whether Moore violated the law by taking ailing Nine-Eleven rescuers to Cuba for treatment.
Moore says he doesn't take the investigation lightly, and wonders why the government is doing it now -- when it could actually help promote the film.
"Sicko" premieres in the U-S June 29th.
