The Omen

The spawn of Satan takes center stage in the classic horror flick The Omen (1976). Robert (Gregory Peck) and Katherine Thorn (Lee Remick) are a married couple looking to adopt a child. They think they find the most perfect bundle of joy in orphaned Damien (Harvey Stevens), but that happiness quickly turns into horror when they discover the child is really the son of Satan. By the end of the film, there's a huge body count.
