Hooray for Palm Pictures for having convinced the MPAA’s ratings appeals board to roll back on that R rating they gave Gunner Palace a few weeks ago, and give it a PG-13 instead. The R rating was all over language. The doc, produced and directed by Michael Tucker and Petra Epperlein, is about grunts doing the day-to-day in Iraq. The title refers to a bombed-out pleasure palace once owned by Saddam Hussein’s son Uday, but occupied by the “gunners” after the U.S. occupation.
