Good grief! Movies back to 1984? Gremlins? Earnest Goes to Camp? File cabinets as subliminal twin towers? Maybe I might miss something in the later episodes, but I would think the opening one would contain some really convincing links. What it contains is nuts!
Of course the twin towers are seen in a great number of films - they were two of the most recognizable and visible buildings in NY City. Not only were they appealing backdrops, it would have been hard to film much footage of NYC WITHOUT including them.
