A lobby card for the film.
In The Final Conflict, Damien is now an adult in his thirties, and he’s played by Sam Neill. He has now become the owner of Thorn Industries, a multi-billion dollar company that has revolutionized the food industry, and which is working to solve the world hunger crisis forever. Damien is also the U.S. President’s first choice for Ambassador to Great Britain (after the current guy gets possessed by a black demon dog and blows his brains out). Damien is hot for Great Britain because he has this entirely fictitious apocryphal text called the “Book of Hebron,” which prophesies that Jesus will be reincarnated in Jolly Old England any day now. (Maybe they didn’t have the budget to do a proper Second Coming, with the J-Man flying down from the sky?) But after he sets up shop across the pond, Damien falls for a news reporter named Kate Reynolds (Lisa Harrow); then these Catholic monks at a monastery in Subiaco, Italy find the Seven Daggers of Meggido and try to assassinate him. This leads to a series of hilariously incompetent murder attempts that will have you shaking your head in disbelief. Meanwhile, Jesus is born again somewhere (did you see what I just did there?), but nobody knows where. Lucky for him, Damien knows the birth coincided with a weird astronomical convergence that occurred a few nights ago, so he sends his worshipers out to murder every male baby in England who was born within that time frame. Then Kate Reynolds finds out what the rest of us already know about Damien, and the titular Final Conflict truly begins.
The number one attraction in this film, and the most important reason for anyone to see it, is Sam Neill; he’s literally the greatest Antichrist I’ve ever seen in any film ever. Forget about Michael York, Nick Mancuso, Gordon Currie, or anyone else who’s ever played the Beast in those movies they show on the Trinity Broadcast Network; Sam Neill’s performance here is the gold standard. Rather than playing Damien like some two-dimensional cartoon villain, he plays him like he’s the Gods-damn hero of the movie. He brings so much charisma and charm to the role that he succeeds in making Damien extremely likeable, even when he’s ordering hundreds of newborns to their deaths. Everyone I know who’s ever seen The Final Conflict ends up rooting for Damien somehow (even though they know they’re not supposed to), and they can’t help but feel disappointed with the ending. (More on that in a minute.) The only other performance that’s comparable to this is that of Sir Anthony Hopkins as Dr. Hannibal “the Cannibal” Lecter in The Silence of the Lambs (1991). If there is an Antichrist and he ever tries to take over the world, we’d all better pray he isn’t just like Sam Neill in this movie—or else we might actually want him to take over.

The novelization of the 1981 film, The Final Conflict, by Gordon McGill.
In one scene, Damien and Kate walk through a park and see one of the monks, who’s standing on a soapbox, preaching. Damien notices the monk is staring right at him, and he instantly knows the guy is here to kill him. So he starts surveying the area like a hawk—without breathing a word of his concerns to Kate—and he actually looks worried. Is he concerned for himself, or is he concerned for Kate’s safety should there be an ambush? Then there’s another scene where Damien goes to work right after the Christ child has been born. He’s been up all night because he could sense the birth happening, and Kate catches him at the elevator, asking if it’s okay for her to try interviewing him again. (Her last attempt was foiled by another assassin.) Damien smiles and agrees, and she leaves; then he gets in the elevator, sighs, and slumps his shoulders. I’d like to remind you that this character is supposed to be Friedrich Nietzsche’s Übermensch with a vast array of supernatural powers; and yet Neill sneaks in all of these brief human touches—a look of genuine concern, a tired sigh—and actually makes us care about this evil, rotten bastard…
I hate to blow the ending of this film for anyone who hasn’t seen it, but trust me; you probably want to know about this going in. For some reason, I thought this movie was going to end with a big showdown between Damien and Jesus; surely, that would be the “Final Conflict” everyone was expecting, right? I knew things wouldn’t end well for the Beast, but I figured there would at least be some kind of special effects extravaganza. No such luck; the movie ends with Damien being led into a trap by Kate, and Kate stabs him in the back with one of those nifty Meggido daggers. Then Damien limps away, curses Jesus, and promptly dies. Cue music, roll credits. When I first saw this, I was royally pissed. The film had done an excellent job of keeping me at the edge of my seat for the first 90 minutes or so; but it starts running out of steam real fast during the final 20, and that ending just didn’t seem fair. They went through all that hard work of building up this magnificent character and this huge final battle he’s going to have, and what do they give us? Sam Neill getting stabbed in the back (literally) by the woman he loves. I mean, what the hell were they thinking? I wanted to see Damien and Jesus go “Hell in a Cell” on that shit!
