Had several long NYC layovers back to back and watched them film. They built a fake floor on the roof, so facade the actors are backed up against isn't really the Roosevelt's "ledge." To be completely accurate, it would be "the man on the Roof."

The directors were picky about the colors of the people in the crowd (dark coats). When guests tried to enter the Hotel they sent us a block around back. The NYC Cops were their typical polite & informative selves. The movie types were really rude, screaming and yelling obscenities at tourists who of course crowded in to see what was going on. I can see why they pay such large fees for permits. If it wasn't for the money the cops would probably round up these bunch yahoos and put them on the first plane back to LA.

I think the hotel room scenes were filmed on the 19th floor.
