Continuity mistake: After the spaghetti twister, Flint puts on his lab coat in the elevator and you can see he has his tuxedo shirt on. Then during the building montage, it's a blue shirt, then changes back to the tuxedo shirt when he turns on the car. Also, during the building, the design on the blue shirt disappears.Sammi
Continuity mistake: In the scene where Flint has been persuaded by the Mayor to keep the machine running and is about to enter the food code, it changes to a shot showing his computer screen. in this shot, his computer is using Windows. But in the shot of the same screen where Flint's Father is about to send him the kill code, the computer is using a Mac OS. (00:45:35 - 01:08:05)
Continuity mistake: On the dock, in the shot of the clouds, you can see about 100 hamburgers aimed for the dock (the middle). Yet at the end of the scene when Flint says, "It really works!" only 20 or so hamburgers are visible on the dock. The wind was moving south as seen by Flint's coat blowing in the breeze, so the wind couldn't have blown them in the water. Also, the fact that we see one more shot of the clouds and the burgers (with about 200 more aiming for the dock) makes this impossible.Low Cow
Continuity mistake: In the beginning no-one's shoes are untied, then it shows you they are, and after that they're tied again.
