Described online as being about 'a priest with a haunted past' who's sent to the Vatican to investigate the death of a young nun in Romania, the yet to be released film is already causing a stir on social media.
The 6-second clip in question shows a black screen with the volume/sound image displayed at the centre to trick viewers into thinking their computer's volume controls are playing up.
Just as you put your volume up to top-notch, a scary sound plays and a horrifying nun pops up.
After people complained - and the above tweet was shared over 151k times, YouTube took the video down for violating its shocking content policy.
However, if you're into that sort of thing, the full-length trailer is still up for your viewing pleasure.
