Explain this...
If the hospital was supposed to be so full that they didn't have any room for any more patients, why was every room full of so many empty beds? Why didn't the filmmakers hire some extras to just lay around in all the empty beds to make the hospital at least appear to be full? Instead you have the actors saying how the hospital is so full but the visual images of a bunch of empty beds show otherwise.
"Enough of that technical talk, Foo!"
