Towards the end of the movie when Emily is saying goodbye to Ms. Tilson and Fritz and the camera pans to Emily you can see a dog going across the screen and it looks like it is coming right up to Emily. Then of course there is no dog in the rest of the scene.
In the scene in the greenhouse, characters are seen putting worms into a jar of dirt. This is a factual error, considering the girl puts over 27 worms into the jar throughout the scene. When the camera pans to the full jar, there are not 27 worms present.
