Somewhere between 34-35min in, there is an ad on tv for a show called Video Music Box and it has the New York skyline on it with the twin towers.
There is (blink-and-you-miss-it) 9/11 footage at 6min 15sec.
*A Futile and Stupid Gesture
Around 19min and 49sec, there is a backgorund shot of the twin towers being built. There are 2 shots in this scene.
There is another shot of them at 1hr 20min. They are fully built at this point.
