The Exorcist spawned a series of sequels and prequels that couldn’t agree on where its characters had come from or where they were going. Now it seems the same fate has befallen The Omen, which was one of the other big supernatural horror movies from the 1970s.
The original film spawned two big-screen sequels that saw Damien Thorn, the boy destined to become the Antichrist, grow to adulthood. The third film ended with the Second Coming of Christ and the death of the Antichrist at the hands of his lover, but it was followed ten years later by a TV-movie in which we learned that Damien had sired a daughter in whom his creepiness lived on. (Meanwhile, the TV-movie also revealed, no doubt unintentionally, that the Second Coming had had absolutely zero effect on the world, and that things were still ticking along as though nothing had happened.)
