Albert Brooks in Broadcast News delivers a classic description of the Antichrist:

What do you think the Devil is going to look like if he's around? Nobody is going to be taken in if he has a long, red, pointy tail. No. I'm semi-serious here. He will look attractive and he will be nice and helpful and he will get a job where he influences a great God-fearing nation and he will never do an evil thing… he will just bit by little bit lower standards where they are important. Just coax us along flash over substance… Just a tiny bit. And he will talk about all of us 'really being salesmen.'… And he'll get all the great women.

Along the same lines, Brent Simmons in his blog inessential.com gives us the following:

Whenever I imagine the anti-Christ, I imagine a super nice guy, universally beloved. Well-dressed, clean-shaven—he won’t look like he’s from Hell.

He’ll be charismatic. Philanthropic. It will seem like he cares about you, personally. He’ll have an air of quiet moral earnestness, like Jimmy Stewart or Gregory Peck.

If he makes something (movies, software, soft drinks, shoes) people will love his products. If he’s a politician he will be loved by left and right.

You won’t know he’s the anti-Christ. In fact, he would be the last guy you suspect.

He’ll have a wonderful speaking voice, and you’ll just love to listen to him talk. Everybody will.

The anti-Christ will successfully appeal to our best instincts.

He will enjoy wide bipartisan support. He will in fact be a uniter, not a divider.

He will lead us to become virtuous—and he will make it obvious and easy.

He will get high marks for his authenticity, for being a straight shooter, for being the same publicly and privately, for being unpretentious, for being at home with both academics and truck drivers.

He will solve some giant problem — he may bring peace to the Middle East or end war and suffering in Africa.

He will be reluctant to lead. We will say that we thought they didn't make heroes like that anymore — but we will thank God we have such a man in this century that needs heroes so badly. He will lead us.

When the battle between Good and Evil begins, most good people will be on the side of the anti-Christ. That's his trick.

Using these attributes as my criteria, I believe I have successfully eliminated Ann Coulter, Donald Rumsfeld and Gilbert Gottfried as potential Antichrist candidates. Now, back to the drawing board . . .
