Nobody mentioned "Highway To Hell" with Kristi Swanson and Chad Lowe. The entire movie is about the devil and going to hell. There is also a "devil"-looking character in Nightbreed, but he's only on screen for a few seconds during a couple of scenes.

"Also I remember once seeing a Spanish language film about a Priest who travels around the city going to heavy metal music shops, etc, trying to prevent the birth of the Anti-Christ." = The Day of the Beast (1995) El da de la bestia
Great movie with good directing and screenplay, good actors. It takes you on a ride trough dark comedy and horror. In some point you think they are idiots, then it hits you with horror elements then push you back to comedy. Ending is brutal and done like a masterpiece. Portrayal of the Devil is very good. 8/10 by me.

OK, I know this thread is really old, but I have to add my own favorite movie starring the Devil. This might sound odd because it's NOT a horror film, but check out Highway 61 (Canadian road movie). I won't spoil it for anyone who might choose to see it, but the main plot line involves Satan. Sort of.

Crossroads, where Satan is portrayed by a black man.
O Brother Where Art Thou, where the main villain is heavily implied to be Satan.
The Passion of the Christ, where Satan is depicted by a woman.
The Last Temptation of Christ, where Satan is disguised as a little girl.
Welcome to my Nightmare- Freddy Krueger

justin bieber in never say never is probably the best depiction, and its non fiction!

Viggo Mortenson actually plays the devil in "The Prophecy" with Walken playing Gabriel. And Viggo plays the devil in a very creepy way.
I agree, the best devil is Curry in Legend.
And Mr. Frost was dang good as well. If you believe in the devil this is the kind of way I would figure it. Just like us, but evil to the core. No conscience at all. Totally a manipulator. And being deemed as insane. A basic pyschopath. However, an extremely charasmatic pyschopath.
Al Pacino in "The Devil's Advocate." He was good.
In the end though, for pure entertainment value, I loved curry's devil in legend.

any rosie o donnel movie.

Christopher Walken plays the archangel Gabriel, which isn't quite the devil but almost should be.
And in the movie The Car, the devil is shown as a car. Sort of like Christine, only more powerful. Seriously.
Some people get the idea of double agent confused with double penetration.

Tim Curry beats them all in
Legend

his character, technically named Darkness, used to scare the crap out of me as a kid.

You've probably figured this out, by now, but the Goldblum movie was "Mr. Frost." Never saw it, but I remember reading that it was decent, way back in '91 or so.

Jack Nihcolson played the Devil in The Witches of Eastwick, really good movie too.

Wtf are you talking about?!?! Anton LaVey had no part whatsoever in Rosemary's Baby. None. Zip. Zilch He's a big phony and a D-bag.

The devil in the Ninth Gate makes you want to be a satanist.

YES!!! YES, YES, YES!!! Jeff Goldblume played one of the best modern day devils I have seen.
I had forgotten about this film.

It was called Mr. Frost, and is very hard to find. I saw it when was around 9 or 10 and haven't been able to track it down again. If memory serves me right, he implies he is Satan, but I don't think he was really supposed to be. Although, I was 9 or 10 a long time ago, and haven't had the chance for a reviewing.

I have never seen Lost Souls but the Devil is not a character in Stigmata or Fallen, (spoiler) both of those movies feature possesion by other entities, {a dead priest and fallen angel Azazel}. And while Lucifer/Satan/the Devil are the most dicussed topic in the Ninth Gate, you aren't really introduced to him/her explicitly.
I remember a movie about an insane asylum with Jeff Goldbloom as the Devil, it was a really great performance, but I don't remember what it was called.

GEORGE BURNS in "OH GOD, You Devil!"
and I can't believe no one mentioned Dave Grohl in "Tenacious The Pick of Destiny"
Viggo Mortensen has been one of the best, in my opinion. "The Prophecy" drips with bleakness and ominous presence, anyway, but he really steals the show w/ just a few lines. His absense made all the sequels a little disappointing.

Lost Souls
Stigmata
Ninth Gate

Some other classics of the genre:
Rosemary's Baby
the impregnation scene with the Devil portrayed by Anton LaVey, founder and priest of The First Church of Satan;
The Exorcist
several appearances of a Satanic face (in The Version You've Never Seen);
Bless the Child
a well-done CGI effect in the climactic scene;
End of Days
as another poster mentioned, the Devil inhabits the body of Gabriel Byrne for most the film but at the end appears in his actual appearance via a spectacular CGI effect.

Hi there, thanks for all your posts. I actually happened upon a book called The Satanic Screen by Nickolas Schreck (sp), that is all about the Devil and Satanism on screen and includes entries for Warlock (both the films), Evil Speak, Devil's Rain, Blood on Satan's Claws, etc. It is missing quite alot of other films, but the essentials are there.
Hope this helps anyone else with a similar diabolical interest.

theres a movie called "Prince of Darkness" by John Carpenter which shows the Devil as a big jar of liquid, and you getto see the hand of his 'father' Anti-God. Theres also 'Evilspeak', and 'Mirror, Mirror' which I thought were pretty good.

a movie called "The Unholy"it was recently on on demand

Harvey Keitel was the reigning Satan, but Rodney Dangerfield was the original Satan, passing his title down to his son when he got old.
I'm old enough to know better but too young to care.
