When the two filmmaker-terrorists were trying to convince Michael Malone that Aziz was an actual terrorist, Michael had several flashbacks of Aziz acting suspiciously. One of the flashbacks was of Aziz dancing at a party with explosives around his waist. This scene was not in the released version! Michael "recalled" something that had not happened. (Or maybe, this being a Zucker film, it was a joke!)
The pew in St. Paul's chapel that the Washingtons used during President Washington's 15 months in New York is actually against the north wall. The movie puts it in the middle of the church.
Some viewers claimed that Hitler appears to be wearing a "wedding" ring on his left hand during his 1938 meeting with Neville Chamberlain, despite the fact that Hitler was unmarried until the day before his death in April 1945. However, as the custom in Austria and Germany is to wear the wedding ring on the *right* hand it may not be a "wedding" ring at all.
After Michael Malone is escorted into the concert at that end of the movie he sneaks away as the soldiers are distracted by the fireworks. On the floor you can see they are "trampling" an American flag. This is part of the extended scene which can be found in the DVD's bonus features.
A scene in the NYC subway station at Madison Square Garden (34th St.) shows a sign for the 2, 5 and "S" trains. The 5 and "S" do not stop there. It should read 1,2,3 trains.
Patton speaks dismissively of his portrayal in Patton (1970) ("That Patton was an actor!"). And yet throughout the film Kelsey Grammer speaks in the gruff, gravely voice that George C. Scott used in that picture. In fact, the real historical Patton spoke in a sharp, nasal, and slightly Southern accented voice.
