If you rise and shine to the sights and sounds of helicopters darting over Manhattan tomorrow: don't fret. We just got word that "a movie shoot will be taking place in the vicinity of 12th Avenue and 23rd Street in Manhattan from 7 a.m. to 7 p.m." and you should "expect to see filming activity in the area including helicopters making sharp turns and maneuvers." If only Air Force One gave this kind of warning. Send us photos if you see the action; and try to figure out which one of these movies currently filming here it might be... perhaps the mysterious Untitled!
