a few doors in film

These films are completely different to each other however, they both use doors effectively.

The shining uses the door as a path to the unknown horrors that lie behind. The Axe in the door conjures a feeling of terror and insecurity (a breaking down of defenses). The 'REDRUM' door has a horror/ shock aura. In the film, blood gushes out of a door, possibly the 'REDRUM' door (something which i cant remember too well) which creates horror which profoundly effects the audience and characters involved.

The bottom image is something completely different. Within Monsters Inc., the doors are used as a pathway to a different land. The monsters use doors as a portal to the human dimension. The door leads to the childrens rooms via the closets.
