This is a list for those interested in good entertainment without letting the brain go donut
1. The Prophecy
the best example of how an occult world works. And its funny, thrilling and stylish!
2. The Prophecy II
The sequel works out the religious themes in deep, because you already know the occult world from the first movie.
3. The Prophecy 3: The Ascent
The conclusion of the angelic tale. A classic, highly detailed messias-plot with great Hong Kong style fighting scenes (really!).
4. Highlander - 10th Anniversary Edition
The one and only. Why occult? You have a hidden group with ancient rules that noone questions or breaks.
5. Poltergeist 2: The Other Side
Hidden in the plot they merged two original american occult lores: Lovecrafts "white" Chtulu-myth and the american-indian "native" occultism.
6. The Prisoner
See them all. You will find everything: Magic, scientology, occult groups, brainwashing, trickster work, wizardry and enlightenment.
7. Excalibur
Excalibur tells you 3 stories: The plot itself, the pictures (look for "frames" and "openness") and the characters as archetypes. This movie is a must!
8. Conan the Barbarian
The first Conan movie revokes perfectly R. E. Howards mythical Hyborean setting, which itself again lies in the Lovecraft universe. The ultimate classic fantasy movie as well.
