Did Michael Moore, whose documentary “Sicko” was rapturously received at yesterday’s Cannes Film Festival, take some, uh, artistic license in filming the film’s most controversial segment, in which he took ailing 9/11 responders to Cuba for medical treatment? My esteemed colleague Susan Edelmantalked to three of them (pictured here with Moore) for an article in today’s Post. “The 20-minute segment of the film devoted to Cuba seems to portray the trip as a ‘reverse flotilla’ – but it’s purely for show,” Sue writes. “The responders told The Post that Moore rented three charter fishing boats in Miami, loading crew members and sick people — about 10 to a boat. In the movie, the boat is seen heading out to sea, presumably bound for Cuba. But in reality, the boat made a U-turn to Miami, and Moore’s group later boarded a commercial flight to Cuba.” Sue adds that Moore, who has been accused of playing fast and loose with the facts in the past “boasted he’d pay $10,000 to anyone who found inaccuracies in his ‘Fahrenheit 9/11,’ and added last week that ‘every fact in my films is true.’ ”
