May be a challenge, butI’m looking for any movies, particularly those that aren’t likely to have been seen, about #exorcism or interaction with demons. Anything from any language is good

If the title contains the words Possession, Exorcist or Exorcism in it, I've seen it.

I like these :

The Sacrament
The Seventh Day
The Possesion of Michael King
The Cleansing Hour
The Old Ways
The Wailing
Noroi
Host
The Rite
Incantation
