Other mistake: The construction of a staircase does not require a large nail at the site shown on the steps. Furthermore when Emily snags her clothes basket on the stairs it lifts a small nail up. How did it grow into a 2 inch fat nail?

Factual error: Grain engulfment is not depicted in a scientific manner. It is not possible for engulfment to happen without a valve being opened at the base - which has not been shown in the movie when the boy falls in the grain storage. It is very unlikely that two engulfments will happen so close by in the same storage - if so, they will converge quickly. But, the movie shows both victims help each other one by one. They succeed in 5-10 seconds. Engulfment become entrapment in less than 20 seconds and require more than thrice the body weight to pull some one out (unlike one kid being able to pull other one out while both are on the grain). Finally, they both sit on the door and avoid entrapment.

Suggested correction: It's possible for grain to look sturdy but not be underneath so the engulfment could have possible. But you're right about them not being able to pull each other out.
Well observed. It's a factual error.
I jumped into grain hundreds of times. It is not possible without the grain moving underneath.

Lee Abbott: Of course I do.
Marcus Abbott: You should tell her.
Question: If the waterfall prevents the creatures hearing them, why not live there?
