Definitely CHILDREN OF THE CORN! I remember watching that movie probably around the age of 10 or 11. My family played on my fears and thought it was funny to terrorize me. I would go upstairs to use the restroom; they would yell "Malachi!!" Which would cause me to jump down to our stairwell landing (not sure I touched a single step) resulting in a family member of my choosing to escort me to the bathroom and stand outside while I relieved myself in peace. I am now 30 and still have fears of what is lurking in the middle of all those corn fields.
Did I mention I live in Iowa?
