As cautious as we are about recommending trailers these days, OnlyForKoolKids advises you to take a look at the teaser for forthcoming apocalyptic-esque horror Grim Night. We say ‘forthcoming’ as the film hasn’t actually been made yet –  the (rather excellent) promo footage was put together to entice a studio to buy the full length feature, and on the back of it Universal has duly obliged.

Presenting a similar vérité style to that seen in director Gareth Edwards’ Monsters, Grim Night appears to be the tale of an annual event where, for one night only, creatures known as ‘Grims’ appear and kill anyone who isn’t safely behind closed doors. Whether the Grims are supernatural spectres or alien invaders is not clear yet, but presumably all will be revealed once the cameras start to roll proper.

A word of warning: don’t watch the trailer too many times, or it starts to look like a film about a gaggle of itinerant crack addicts who forgot to take their witches costumes off after a particularly intoxicated Halloween night. With that in mind, check it out:
