Perth Cinema Accidentally Shows Horror Movie Trailer Before Peter Rabbit

Well... Peter Rabbit *does* love mischief.

There's nothing better than a relaxing trip to the movies, especially if it's a cute family outing to see something uplifting. At least that's what a cinema-full of Perth locals believed.

According to the best story you'll read today in WAtoday, a screening of Peter Rabbit started like you'd imagine. You get a few ads, maybe a trailer for a family flick or two, and then the tone definitely changed when the cinema accidentally showed the trailer for the upcoming horror movie Hereditary starring Toni Collette.

Collette's film has received a ton of buzz after it premiered at the Sundance Film Festival earlier this year. It has been called a "weighty horror," a "harrowing story" and "a new generation's The Exorcist".

Basically it's not the kind of trailer you'd want to show a group of unsuspecting adults, let alone a cinema packed with kids.

According to one woman, who was in attendance during the stuff-up at Event Cinemas Innaloo on Anzac Day, at least 40 kids in the screening. They were expecting an adorable fuzzy rabbit romp, but were first treated to two minutes of a tense horror fantasia with a trailer that includes a teenager slamming his head on a desk, a young girl putting a pair of scissors to a bird's neck and just an array of terrifying visuals.

Hereditary stars Collette as a woman whose mother passes away leaving the family to discover secrets about the woman they thought they knew, and a "sinister fate" they've been born into. It also stars Gabriel Byrne, Alex Wolff, Milly Shapiro and Ann Dowd and is scheduled to open in cinemas in Australia June 7.

Peter Rabbit meanwhile is an adaptation of Beatrix Potter's iconic, mischievous rabbit Peter and his sisters Flopsy, Mopsy and Cottontail as they adorably terrorise Mr McGregor's vegetable patch. The live-action, animation blend stars Rose Byrne, Domhnall Gleeson, Margot Robbie, Daisy Ridley and James Corden and is now screening.

Just... watch out for those trailers.
