Lions Gate Films and IFC Films, the movie's distributors, said an appeals board for the Motion Picture Association of America rejected their request to reduce the rating to PG-13.
The R rating prohibits those 17 and younger from seeing "Fahrenheit 9/11" without an adult.
The movie, which won the top honor at last month's Cannes Film Festival, was rated R for "violent and disturbing images and for language." The movie's images include an Iraqi man tossing a dead baby into a truckload of bodies, Iraqis burned by napalm and a public beheading in Saudi Arabia.
Dude, that's so acceptable for 13 year olds to see! The MPAA is so obviously part of the Vast Right-Wing Conspiracy (tm)!
