Ever since watching Netflix's "Bird Box", I've been watching a lot of these videos on YouTube to see how much stuff I missed in the movie. One of the videos I came across had one detail I COMPLETELY missed, plus had what the demon was SUPPOSED to look like...but wasn't used.
You can watch the entire video below, but I cued it up to something I didn't even notice. It has to do with the couple that leaves the Douglas' house to find their children.
SCROLL DOWN TO SEE THE DELETED DEMON
I also read about how originally they were gonna have a scene that showed the demon, but decided to cut it.
I cued up the video below to where it shows the early stages of the prosthetic that was gonna be used!
