Technology in the Service of Terror

"We wanted every portal to look like an open wound in reality itself. Not just a dimensional door, but something that hurt to look at"

The Art of Making the Supernatural Believable

Maintaining the balance between Lovecraftian horror and 80s aesthetics was like mixing Coca-Cola and Mentos: explosive but delicious. The integration of digital elements with practical sets was so perfect that even the actors doubted what was real.
