Omen 5: 2abomination

I remember seeing a column around the time that the movie The Final Conflict came out that indicated that 20th Century Fox had originally intended there to be 5 Omen movies but had changed their minds when Omen II did not do as well as expected at the box office. I have often wondered if these two books by Gordon Mcgill were based upon what the original movie plan had been. Consider this: In Omen I Bugenhagen gave explicit instructions on how to use the 7 daggers. Specifically the first extinquished life and the others were to be placed in the shape of a cross on hallowed ground. At the end of The Final Conflict this did not happen and it is only in this book that the correct procedure is applied. I personally think these books would have made much better movies than the wretched Omen IV on the USA network a few years later.
