Can anyone tell me the tune to the Omen and King Artur. Both are the same. First answer gets full points?

Answer 1

I doubt they are the same. The theme from The Omen is called Ave Satani by Jerry Goldsmith.

It is often mistaken for O Fortuna by Carl Orff, from his oratorio Carmina Burana, which may be the music from King Arthur, although its original score was composed by Hans Zimmer.
