Wich are your favorite movies about the Occult?

[Kepler]

Midsommer was great for iconography and rituals

And effective in the way it raises energy for an actively participating viewer identifying with the cultists. Like a witness to a dramatic ceremony from the way it builds with the movie hitting those reference points.
With the season approaching it's getting time for a rewatch.

I have to add Nosferatu (2024) here, because that movie really seems to depict a ritual going wrong. Thinking about energetic double (or twin, shadow, etc.) made me realize that the girl summoned one to help her in hard life, but then turned against it... and so the shadow, pretty powerful one, simply reflects that back to her. (I assume that in the first scene she is already crying for help to get rid of Orlok aka. her shadow...)
