In terms of movies, I’d add the following as well:

Angel Heart - sort of akin to Jacob’s latter, there are valuable things to mine for a Harrowing

Stir of Echoes - probably more useful for an Orpheus story or the forthcoming World of Darkness: Ghost Hunters, it still has some neat elements.

Insidious 1 and 2 - the scenes inside of “the Further” are totally worth the price of admission themselves for a cool depiction of the shadowlands.

The Frighteners - wanna know what it’s like to go up against a Spectre?

House - a comedy-horror...
