Factual error: As Shrek is sitting near the sunflowers field and staring at the Duloc (and day becomes night), we don't see the cathedral anywhere. It should be visible as such a big building, due to how big it is seen later, it should be very distinct over the houses' roofs.
Factual error: In the scene where Waternoose and Sully are talking, Waternoose gets himself some "coffee", which is sludgy and thick and takes quite a while to pour from the machine. Seconds later, he takes a very quick sip. Since the liquid was so thick and there was little in the cup, it would be impossible for it to pour that fast.
Factual error: At the start of the film Chihiro's father slams on the brake to avoid the statue in the road and quickly stops. There are three pedals, meaning that this is a manual transmission car (a pedal e-brake would be positioned differently), but he only puts his foot down on the brake and doesn't touch the clutch. Whilst he would stop, there was not enough time for the car to stop as quickly and as smoothly as it did. The car would also stall out but it doesn't.
Factual error: When Cindy is giving her "fossil-to-chromosome ratio" report, she calls her model dinosaur skeleton a plesiosaur. However, the skeleton is of a bipedal dinosaur (likely a hadrosaur, judging by the "duckbill"), while plesiosaurs were aquatic reptiles with flippers instead of feet.
Factual error: At the beginning, after the blue virus-monster appears, some telephone wires wrap around a scientist's arm. There aren't that many wires in in a normal telephone, nor are they that thick.
Factual error: Milo says Audrey is a "teenager". Which she is, but this is 1914! People didn't use that word back then. He probably should have said "adolescent" or something.
Factual error: There's not enough soda in two cans to soak two ninjas.
