People having visceral reactions to horror movies is nothing new (see: The Exorcist; also see non-horror but disturbing new movie The Tribe from this year that made people faint). But it might be safe to say that Bite is the most horrifying movie of the year.

At the world premiere of the new film at Fantasia International Film Fest a couple weeks ago, people were scared so out of their minds that an ambulance had to be called. Bite's Facebook page posted the below photo of the scene outside the screening, and this dispatch from an attendee: "I leave the BITE premiere for all of ten minutes and the following text lights up my phone: "2 people,fainted. One girl is puking and another hit his head on stairs". Truth." Apparently they were also handing out barf bags at the screening, which clearly came in handy for at least one audience member.

SO WHAT THE FUCK IS THIS MOVIE ABOUT?

AND WHY IS IT SO GODDAMN HORRIFYING?

Bite is about a bride-to-be who goes on a bachelorette getaway with her friends when she gets what she thinks is an innocuous bug bite. Instead, she comes home and starts transforming into a bug, with pus-filled scabs covering her body. Ewwwww. She starts showing other terrifying insect-like tendencies as well, like hive-making and feeding on others. This sounds gross as hell (thinking there will be a lot of bodily fluid  stuff), but now it feels like a dare—there's NO WAY I won't watch this movie now.

Think you can stomach it?? Start with the terrifying trailer first:
