Blooper

When Henry Black is hammering in the middle of the night, in one scene the nail holding the wheel is partially hit into place, he asks for 10 more minutes but the next scene shows the nail in all the way with no further hammering.

When Anton Yelchin's character bangs his head into the wall and it goes through the side of the house, that's impossible as shown. The cedar shake siding is not shown as held to the side of the house with anything, whereas in reality is has to be nailed down. The house would have some cladding such as plywood to nail the shakes to, and then a barrier such as asphalt or homewrap, at the very least. It is not possible to make a small hole in the interior wall and push one shake off the outside of the house in the same location.
