This looks pretty horrifying. If you don’t think so, you haven’t seen the opening, which is BRUTAL and I advise you not to watch if you’re pregnant or you’re a loved one of someone who is. Then again, I read a series of posts on the IMDB boards for INSIDE that basically said this:

Guy #1: Hey, my wife is pregnant and about 6 months in, but we want to rent and see this movie together, would you recommend it in our case or is it too potentially upsetting?
Me: Hey, guy #1, when it comes to watching Inside when your wife is due to give birth in a couple months HOW ABOUT NO? I saw it when I was not pregnant (never been pregnant or plan to) and I was so scared that the last 5 minutes I actually started to cry, OK? And you’re talking to a very, very jaded horror fan who owns copies of some of the most fucked-up movies, from all over the world, ever made. You COULD watch it now, but I would not recommend it, in fact I literally cannot think of a worse movie to watch when you’re pregnant (and yes, I’ve seen the rare uncut version of “A Serbian Film”. That’s my advice.
Guy #2: yeah, I’d say it’s fine. Go ahead and watch it together. I saw it when my sister had just found out she was pregnant, and it didn’t bother me.
Me: No, seriously, unless you’re popping Xanax, which you can’t because you’re pregnant. Oh, and just to let you and your third-trimester pregnant wife know, even without the whole “woman attempting to cut out the heroine’s baby with a giant pair of shears” plot line, it’s one of the bloodiest, most gory movies I’ve ever seen. By the last half hour of the movie, everything/everyone that can be covered with blood, IS covered in blood. When I watched the “making of” extra, several times the main actress (in her 20s) had to take a break because she couldn’t stop crying when a scene was being set up. Just wait. Even the R-rated version is very brutal.
Guy #1: Yeah, I’m gonna rent it now, she says it won’t bother her.
Guy #2: Cool, dude. Hope you guys enjoy the movie!

So anyway, yeah, well be watching this when it comes out on VOD April 18th. I’ll post the link to the opening some point soon– if you must see it RIGHT NOW then Dread Central has the clip posted in HD (with a bunch of warnings prefacing it).
