Patton speaks dismissively of his portrayal in Patton ("That Patton was an actor!"). And yet throughout the film Kelsey Grammer speaks in the gruff, gravely voice that George C.

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 waste. This scene was not in the released version! Michael "recalled" something that had not happened.
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.

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.
