After nearly a month in theaters, Michael Moore’s documentary “SiCKO” - a movie about the expensive, inefficient U.S. health care system - finally got a wider release this past weekend. It’s now showing at more than 1,100 theaters in the country, up from around 700. Thus far the film has raked in $19 million, making it one of the top five grossing documentaries of all time, according to michaelmoore.com. That’s a pittance compared to $222 million worldwide earnings of “Fahrenheit 9/11,” Moore’s last film, but it’s not a bad take for a movie that cost $9 million to produce.
