The principal photography begun at the 10:00 am, and ends the same day, at 8:00 pm.
Originally, the whole film will feature some tracks from the "10 Cloverfield Lane" music from the motion picture, from Bear McCreary, but the idea won't fit in the directors conception for a "true story". Anyway, some notes from the track "Michelle" and "10 Cloverfield Lane" can be eared in some parts of the movie.
The book that Alice is reading, is 'Joyland' from Stephen King.
The final scene from "The Burial" can be seen a few seconds on the televisor, when Alice is watching it.
The name of the TV channels that shows on the TV, are named in honor the 'company' name.
