On the dashboard of Burt and Vicki's car is a copy of Night Shift, the Stephen King short story collection in which Children of the Corn originally appeared.
The tagline "And a child shall lead them" comes from Isaiah 11:6 in the Old Testament, which reads, "And the wolf shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them."
Though real corn was used for most of filming, polyurethane corn had to be used for the more difficult action sequences.
When asked by a fan how the effect for the burrowing "He Who Walks Behind the Rows" was created, special effects artist Wayne Beauchamp revealed that it was accomplished thanks to a special device called the "Turtle" - a wheelbarrow bucket flipped upside-down with added wheels. The device was set in rails in a trench, attached to a pulley system connected to a tractor, and then covered in a tarp with a layer of dirt and vermiculite on top. The tractor would pull forward and the Turtle would move beneath the tarp, creating a mound of earth that traveled from one point to another. The trench ended in a sharp hill, giving the illusion that the creature beneath was diving deeper into the ground. Beauchamp added that the trench itself was dug by a local group of Boy Scouts who were interested in learning how films and special effects were made.
In the original story, Isaac and Malachi's real names were William Renfrew and Craig Boardman, respectively.
The Song "Disciples of the Watch" by American Thrash Metal Band Testament was inspired by this film.
