Factual error: The German police cars show the number "109" as the emergency telephone code, but the German code to call the police is "110" and "112" for the fire brigade / rescue.
Factual error: When the team's supposedly in Frankfurt, Germany, you can see yellow cabs. Cabs in Germany are always colored sort of dirty white/beige.
Factual error: In the movie, the United States Embassy is in Frankfurt. The embassy is actually in Berlin - any foreign dependency in cities other than a nation's capital is a consulate.
Continuity mistake: In the photo booth scene, Face gives Sosa a phone. Later on, after Hannibal had made a call to Sosa to set up a meeting, Sosa sees an incoming phone call from Face, on the phone presumably given by Face. That phone is a Nokia E71, which is a normal candybar phone. But when she receives the call, the candybar phone suddenly becomes a slider phone.
Factual error: During the Frankfurt scenes, a lot of cars have a license plate starting with "FF"; eg. FF - AB 1234. FF stands for the eastern German "Frankfurt/Oder" (Frankfurt at the Oder River) and NOT for the west German Frankfurt/Main (Frankfurt at the Main River) where the financial district and the large airport is. There is a distance of 470 kilometers (292 miles) between those cities.
Continuity mistake: After Hannibal rescues Murdoch from a psychiatric ward, they are escaping in a military van. Sosa fires several shots at the vehicle and sparks start emerging from the left rear wheel. In the next shot, as the van approaches an airplane, the sparks are now emerging from the rear wheel, then when the vehicle stops no tyres are flat .
Revealing mistake: A couple of times throughout the film, when B.A drives the van, he wheels spins it. The camera goes to the wheel of the van spinning. It's a silver wheel, but all four wheels of the van are jet black and not silver.
Continuity mistake: When Hannibal is put inside the crematorium oven, the door at his feet closes like a steel blind, with one blade going down over the first blade, to create a double door. However, when Hannibal opens it by kicking the door with his feet, the door opens upwards like a crappy trap door. If it were a back door he should have opened it with his head. There was no space for him to turn around 180º.
Other mistake: Towards the end when we see one of the $100 bill plates up close, the plate is not of any money ever put into production in the US. While I know most movies do not try and use actual money, there are things that don't match how real money is made: serial numbers are not on the plates, circle around Ben's head doesn't go to the border, "The United States of America" is missing above the "100" on the left, just to name a few.
Revealing mistake: When the 2nd BMW SUV is blown up on the dock, you can see the underside of the vehicle which reveals how they removed the drive shaft to help reduce the weight of it in order to flip it easier. There are also 2 jets of white gas seen coming from 2 pipes under the rear bumper which are what launched the vehicle end over end.
