Michael Moore, the US filmmaker known for his controversial documentaries such as “Fahrneheit 9/11� and “Bowling For Columbine�, has launched his latest movie at France’s Cannes Film Festival.

Called “Sicko�, the Moore’s documentary is investigating the state of US healthcare system. Moore, who already won a Palme d’Or for “Fahrneheit 9/11� described “Sicko� as “call to action�.

“Sicko� is presenting the personal stories of people who have experienced some of the problems of US healthcare system. For example, Moore is investigating the case of elderly couple whose massive healthcare debt eventually forced them to move out of their house and into their daughter's basement.

In another story, Moore is talking with a woman who was involved in a head-collision. After being treated at the hospital, she had to pay the cost of ambulance from the accident because the insurance company rejected her claim, stating that she had not arranged prior approval.

Also, the documentary shows Moore taking rescue workers from the Sept. 11, 2001 terrorist attacks, who are suffering from symptoms believed to be connected to their rescue work, to a naval base near Guantanamo Bay, Cuba.

Because of his trip to Cuba, Moore is facing a fine or jail because, according to United States Treasury, he broke the trade embargo, as he did not have a license to travel to this country.

According to media reports, the movie received a warm welcome at Cannes Film Festival and it is one of the favorites. The movie will open in US in late June.
