Hey, It's That Guy!: Yes, at 58:40 on the DVD that is New York Mayor Rudy Gulliani passing the car Gedeon is riding in. They even slow down the footage to give you more time to spot him.
Unintentional Period Piece: This film captures the last major catastrophic event from a time before cell phones started doing more than allowing people to make phone calls and send texts. In any footage of people in the streets following the attacks, only a handful of people are talking on cellphones, and no one has their phone held up in the air to record the carnage. (Most phones didn't have still cameras yet, much less the capability to film video. YouTube didn't exist at the time, either.) For the record, the Indian Ocean Tsunami of 2004 became the first disaster where a majority of first-day footage came from cellphone users.
