Pet Sematary co-directors Dennis Widmyer and Kevin Kölsch have revealed that they expect the movie to be rated R.

The pair, who previously directed Starry Eyes, are not coy when it comes to the dark weight of their upcoming take on the beloved Stephen King story.

“It’s a dark f--king movie,” said Widmyer in an interview with Bloody Disgusting. “It’s Pet Sematary, this is not… a lot of Stephen King’s work is, I love it, it’s sentimental. The good guys win. Even at the end of The Shining, Wendy marries Dick Halloran, people forget that, that’s not in the movie, but Stephen King has a heart. And a lot of his work has a heart. This one… he like put in a drawer for a like a year and he felt really disturbed by what he had written. So, you have to make that story.”

The recently released trailer hints at the dark nature of the film, and suggests just how terrifying things could get. One of the producers on the film, Lorenzo Di Bonaventura, told the horror movie website that he’d be genuinely shocked if the movie didn’t receive an R rating.

Pet Sematary centers around a family that moves into a quaint farmhouse near a remote patch of woods. The family learns about the supernatural aspects of a local plot of land that could give them a second chance after a great loss. They don’t heed the warnings about the magics of the area, though, and a special breed of evil emerges.

A previous adaptation of the story was released in 1989. That film was also R-rated and went on to become a major commercial success.

Directed by Kevin Kölsch and Dennis Widmyer, Pet Sematary stars Jason Clarke, Amy Seimetz, Jeté Laurence, Hugo and Lucas Lavoie and John Lithgow. The big screen adaptation of the Stephen King novel opens April 5, 2019.
