Other mistake: In the scene where Sly and his female partner are using the speed gun, a speeding car drives past. The female cop is pointing the speed gun towards the sky and not at the car, so it would never give a reading. (00:19:30)
Other mistake: In the original film, "Ivy" is not the character's actual name, but is just a nickname she goes by that her friend Sylvie makes up. We never find out her real name. In this film, we briefly see the character as a child, and she's inexplicably called "Ivy" as though it has been her name all along. (Likely done just to make it clear to the audience that she's the same character, but still it makes no sense.)
Other mistake: When Will is in his room reviewing books and flipping pages, the book "Help Yourself" is completely blank. (00:27:00 - 00:28:00)
Other mistake: In the shot where the elevator door opens after the screenwriter hears the music playing, the control panel (for the basement) shows the building goes up to eleven floors. When the elevator opens on Floor 5, we can see the control panel on this floor only goes up to ten floors, despite being in the same building. (00:41:55)
Other mistake: When Roper and McCall switch places in the tram scene, Roper steps up on the seat while McCall grabs the wheel. Despite the delay between Roper's foot leaving the gas pedal and McCall getting into the front seat, the car does not slow down. (00:57:20)
Other mistake: The doughnut shop customer's gun was pointed upwards and away from the doughnut shop employee's head when it fired. (02:04:37)
Other mistake: The Jackal only test fires 1 shot at the pumpkin target before he tells Lemont to run for the speed test. When he's siting the weapon in on Lemont, the read out on his screen shows that the number of shots fired is 2. (00:58:55)
Other mistake: When they have the baby Rex and the parents approach for the infant, there's an outside shot of the T-Rex roaring as Ian moves away to the other side. After he does that the Rex on the other side silently roars, then that same roar bit is repeated from inside the trailer in the very next shot, but the roar is added in, showing repeated takes.
Other mistake: Towards the beginning when someone is looking at a newspaper about the airliner being blown up, there are nonsense articles on the paper and pictures of people that don't match the names under them. With some white guy's picture over the name Michael Jordan on the left of the page, and then on the right a picture of a white woman with the name Will Smith under it.
Other mistake: When Luther is driving the Senator to the White House it is raining. But there is a shot of Luther from the outside front window and the window is perfectly dry even though side and rear windows show that it's still raining.
Other mistake: When Mimi wants to dance, and she wipes the diner table clean, the table is about 2 feet square. When Mimi and Jimmy dance, they are 6 feet apart, despite dancing on that small table. (00:39:00 - 00:39:40)
Other mistake: When Abby and Costner is on the run and hide in the forest. They kill a Holnist and capture his horse. When leaving, they still only have one horse.
