The Omen is a horror film franchise beginning in 1976. The story was originally written by David Seltzer, who chose not to continue the series after the first novel. After the third film was produced, a fourth was made-for-television in an attempt to revive the series, but it was received poorly. Three documentaries regarding the series have been made: 666: The Omen - Revealed (2000), The Omen: Legacy (2001), and The Curse of The Omen (2005).
