Saw a trailer for a movie like the possession of michael king and can't find it now

I saw a trailer for a movie a few months ago that looked kinda similar to the possession of Michael King. Instead of recording himself as proof that the supernatural wasn't real like Michael King did, the guy in the movie I'm looking for wanted to record and document what it felt like to be possessed and undergo an exorcism.

Ring a bell with anyone?

Sounds like the Possession Experiment.
