Continuity mistake: At the beginning of the movie, you see that the baby Matilda's eyes are brown, but they change colour to blue when she's in the car.
Suggested correction: It was just the lighting. The sun was shining through the window in the morning.
Revealing mistake: When Matilda telepathically makes the TV explode, you can see what looks like parts of an explosive hidden behind the screen.
Suggested correction: Clearly no sign of it.
Suggested correction: There is no view of the explosive.
Suggested correction: When the TV set explodes, it's a close-up of the screen and no device is seen. When it changes to a wider shot of the actual explosion, the glass breaks and some components of the TV set are shown. There is no way to distinguish between what is a component and what is, as you say, an explosive.
Factual error: When Miss Trunchbull gets pushed onto the globe by the boy she just threw out the window, it shows Japan south of Asia. Japan is really east of Asia.
Suggested correction: Japan is shown correctly, with Korea west of the south part of Japan, China west/southwest of Korea, and the Philippines to the south of Japan. You can also see the Russian island and peninsula just north of Japan. It is a real globe.
