Other mistake: When Joe (The American Ninja) pushes the girl out of the moving truck, one sees the stuntMAN (playing a girl) mis-time the fall and land on a large clump of rock and dirt, after which, before the scene cuts, we see the stuntman curl over in pain. Obviously a very painful fall for the stuntman and a very very funny scene for the viewers.
Other mistake: In the race scene between Milner and Falfa, you can see exhaust smoke coming from Milner's car, but in a previous scene the station attendant mentioned Milner taking the header plugs off. By taking the header plugs off, his exhaust is running from the headers and you wouldn't see exhaust coming from the tail pipes. (01:03:15)
Other mistake: During one of the recording studio scenes, there's a short segment that shows a bunch of VU (audio level) meters close up. The very first meter in that sequence is not a VU meter. Its from of an old HF (High Frequency) Amateur Radio transceiver; The scale is marked for RF, SWR, and ALC. I'm suspecting that someone involved with the post production editing is a Ham.
Other mistake: In the scene after De Niro's car explodes, they show him being put in the ambulance feet first. Patients are always put in head first.
Other mistake: In the battle for Fredricksburg you can see streaks in the sky from jets.
Other mistake: In the scene when the Zulu warriors have broken through the roof in the hospital. The British make a hole and escape through it. You can clearly see the hole that they are going to cut open because it is a different color.
Other mistake: When Hilts and Ives are taken down to the cooler for the very first time, just after arriving at the camp, watch the wall as the door is closed by the guard behind Ives - it very obviously moves as the door slams shut.
Other mistake: The little girl elf pours Santa a mug of hot chocolate, but if you watch closely there is nothing in the mug when he drinks it.
Other mistake: During the time capsule recovery ceremony, there is a man standing next to Nicolas Cage, who pulls out his cell phone to take a picture of the ceremony. However, he's holding the cell phone wrong, pointing the camera towards himself.
Other mistake: When the firefighter is fighting with the arsonist, the gas line is disconnected from the fireplace. Just before the dramatic explosion, the gas line ignites. This is incorrect because the fire would have started from the outlet to the gas (from ignition source to fuel source).
Other mistake: In the scenes after Giovanni Ribisi is arrested, his looks are constantly changing. In scenes where he is talking to Vin Disel his face is very fat. When he walks by Abby's desk he is thin again. If you get Boiler Room on DVD you'll see an original ending where Ribisi is thin all the way through the end of the movie; Because Giovanni was preparing for a film that required him to gain 30 something pounds, the scenes that needed to be reshot for a different ending are very defined.
Other mistake: When Bowie and his men first enter the Alamo, Travis calls for the colors ceremony and the detail marches to the flagpole. One section is ordered to "halt", then the order "about face" is given. However, the detail does a "right face" instead.
Other mistake: In the opening scene of this German movie from 1944, a panoramic view of the city of Potsdam is shown with the subtitle "Potsdam 1813". In the background, the two high radio masts of the Potsdam Military Communication Central can be seen very clearly before the sky.
Other mistake: In the party scene, there's a band playing on a stage. You can hear a big band playing, with lots of horn players, but the music that is heard has absolutely nothing to do with the players, who play guitar, accordion and double bass.
Other mistake: After Langdon saves the last of the Preferati by diving into the fountain, he heads off to St. Angelo with dry clothes. Since it is only ten or fifteen minutes later, his clothes should be soaked.
Other mistake: When Mimi is in hospital Lucy stands at the door and Mimi has a tube in her arm. Then when Lucy goes over to the bed the tube has disappeared. Then later it appears again.
Other mistake: When Pumba is singing and they show him as a baby warthog farting in the water killing the butterfly, it is actually a baby Red River hog that is portrayed.
Other mistake: When Josie just arrives to the school and is standing with her back to the car, we see a blonde girl with a short blue dress pass, in the next shot, she passes again. (00:14:55)
Other mistake: When attacking the convoy, the crew rushes forward during the crash dive. Just after a crew member jumps through the hatch after the bow crew compartment, you see someone standing still a second before getting pushed in the view of the camera. (01:31:15)
Other mistake: During the Baer and Braddock fight, when the camera angle is from far away, you can see that Braddock is not actually connecting with his punches on Baer. Yet Baer still reacts like he's been hit. This also true with Baer hitting Braddock when the camera is showing the fight from far away in the stands.
