Q1

Why does Nathan believe his dog Maxine went to Hell?

A.

Nathan's mother playfully teases him that Maxine has gone to Hell for being a bad dog. This comment deeply unsettles Nathan, especially after he begins having nightmares where Maxine attacks him.

Q2

Why does Oralee create a fake grimoire for the ritual?

A.

Oralee invents a fictional classmate named Ike and presents a sketchbook as a recovered grimoire to give the ritual credibility and ease Nathan's fears. She designs it as a way to help her brother cope with his grief and nightmares over Maxine's death, not expecting the ritual to actually summon real demonic forces.

Q3

Do the rituals in Antrum actually work?

Q5

What is the Astaroth rune shown throughout Antrum?

Scholars in the documentary identify a recurring rune throughout the film as being associated with the demon Astaroth.
