WATCH: Is the trailer for Lights Out the most terrifying horror movie trailer ever?
If you're afraid of the dark you should probably give this one a miss.
The trailer for new horror flick Lights Out is not for the faint of heart or weak of bladder so consider yourself warned before you hit 'play'!
It's the latest horror from produver James Wan, the man who brought us The Conjuring (with the second instalment in that series due this summer), as well as the never-ending Saw series and that creepy doll Annabelle.
Leading the cast is Aussie actress Teresa Palmer and features a tortured ghost or ghosts who appear in the darkness but disappear in the light.
And it looks absolutely TERRIFYIING. Here's the trailer, and if you haven't dissolved in a puddle by the end of it, it runs straight into the trailer for The Conjuring 2...
We'll keep you posted on release dates.
