A new thirty second clip from upcoming horror The Nun dropped online last night and anyone suffering from claustrophobia or a fear of being trapped should avoid it.

The teaser shows lead character Father Burke (The Hateful Eight's Damian Bichir) being dragged into a coffin by supernatural forces, buried underground and attacked by the titular Nun.

It is available to watch below.

The latest in The Conjuring franchise, The Nun is a prequel to the 2013 box-office smash. Set in 1951 Romania, a nun (Taissa Farmiga, American Horror Story), a Catholic priest (Bichir) and a novice (Jonas Bloquet, Elle), are sent by the Vatican to investigate the mysterious suicidal death of a nun at the Cârța Monastery.

The Nun is directed by Corin Hardy, whose previous film The Hallow was set in Ireland and centred around Irish mythology. It's also written Gary Dauberman, who penned the recent It reboot.

The viral marketing for The Nun has caused some controversy. A six-second advertisement pops up on YouTube and begins with a volume icon going down. The ad comprises of an unexpected jump scare - an image of the titular Nun popping out at you with full sound effects.

The Nun is out in Ireland September 7.
