Corrected entry: In the scene where Alice shows Ruby (Fool's sister) the pantry, Ruby then turns and walks towards the front door. If you keep your eyes on the actress that plays Alice, you can see her break out of character for a moment and then laugh in the background. (01:26:40)
Corrected entry: Since Roach has been able to elude Daddy for so long, why couldn't he take a few sticks of the dynamite in the house, rig up the front door blowing it open, and set all of the People under the stairs free?
Correction: Roach has been living in a cell and in the walls his entire life. He would have no idea how dynamite works, let alone the mental capacity to conceive such a plan.
Corrected entry: Leroy says to Fool, "Y'all are being evicted, you gotta be out tomorrow at midnight." California law (the movie was filmed in and thus presumably takes place in Los Angeles) requires landlords to give 30 days notice to evict. (00:03:40)
Correction: Couple things: They may have been given thirty days notice, and he was reminding them they had to be out by the next day midnight. Second, even though it is law, some landlords don't follow the law, depending on the likelihood that the evictees won't complain because they either don't know the law, or don't have the resources (especially in low rent districts) to fight for their rights.
Corrected entry: When Fool first goes into the basement and pulls the TV back to hold up the lighter to the slats, you can see mesh over the wood. Yet minutes later, Fool sees one of the people under the stairs reaching through the slats to pull the TV back into position and there is no mesh. (00:27:00 - 00:28:45)
Correction: The diagonal metal grating is not "over" the wood frame casing, the metal grating is actually behind it, on the side of the ones under the stairs. So one of them simply moved the grating within those "minutes later", in order to slip his hand through the wood frame to reach the TV. No mistake here.
Corrected entry: When Fool escapes from the house and calls the police there is an army of cops and child protective service people there yet not one of them even thinks to search the basement or the scorched bullet ridden upper floors of the house.
Correction: Remember, Fool broke into their home. If they tell the cops that,he loses credibility.
Corrected entry: When the police and child protective services people are in the house after Fool escapes and calls them to report abuse, he somehow winds up hiding in a kitchen cabinet while they're there. Why doesn't he just show the cops where the basement prison is?
Correction: Not to sound racist or anything but think about it. Even if Fool did do that who would the cops believe? The white couple that owns the house or an african american boy who knows about the secret only because he broke into the house?
The police probably would, at least, check out Fool's story, but it's likely he'd assume the police wouldn't believe him.
Corrected entry: At almost the very end, when the people under the stairs are finally outside of the basement and begin coming out of the woodwork (literally), there is one man that breaks out of the wall near the floor to try and grab at the wife. In very plain view, the 'V' slit in the back of his mask is visible. Seems the costume poeple hadn't seen the need to tuck it under the shirt or close it up.
Correction: Actually, a little later in the scene you see the front of his face and see that he IS wearing mask that covers the top half of his face, so this is not an error. It was meant to be that way.
Corrected entry: When Fool, Leroy, and their ally are driving around the streets of a suburb near Detroit, there are palm trees along the sides of the road, but there aren't any palm trees in Michigan.
Correction: It is never stated that the film is set in Michigan. I'm pretty sure it is L.A.
Corrected entry: Roach sets off a trap which sends "Prince" sliding through a giant slide to the kitchen. That is almost impossible for Roach to build a perfect slide through the house into a drawer in the kitchen - wouldn't the parents notice it?
Correction: That's because Ruby says "where did that sick f***er go now", making her laugh. She said something funny and Alice laughed. No mistake here.
