Don't mess with the dead or, as the first trailer for "Pet Sematary" proves, you will absolutely regret it.

Stephen King's classic novel gets a new adaptation, having previously made it to the big screen in 1989. The story is the same: A doctor (Jason Clarke) and his family move to a house in rural Maine, where they discover a burial ground nearby in the woods.

When tragedy strikes, Louis turns to his unusual neighbor, Jud Crandall (John Lithgow), setting off a perilous chain reaction that unleashes an unfathomable evil with horrific consequences.

The movie, from directors Kevin Kölsch and Dennis Widmyer, seems to treat King's novel mostly faithfully, except for one big change that is revealed in the trailer. It may prove controversial for King fans, but everything else about the chilling trailer points to an "It"-sized hit.

"Pet Sematary" opens in theaters April 5.
