The most interesting film I have seen, which features Satan is The Masque of the Red Death.
This film was directed by Roger Corman and starred Vincent Price, who always plays these diabolic characters well. I bough my copy on Amazon - it is a Midnite Movie.

There are other films which are good - the films of Robert Fuest, the director who knew LaVey and made Devils Rain and the Phibes films.
Many of the films I like don't reference Satan so directly, but "Satan" forms a sort of background, as in film noir scenery, or is presenced by haunted geometry, angles and the trapezoid, as in German Expressionist film of the 1920's etc.
'Apparition' is mini-series about an exorcist and his fight with demons. It's a nice dark series.
'Antichrist' with Willam Defoe is mentally and physically brutal.
'The Prophecy' movie series is good, although it's more about angels, it does get into some devlish bits.
'The Pick of Destiny' with Jack Black. Of course.
'Nights of Badassdom.'
'Little Nicky' with Adam Sandler. Classic.
2. Evil Dead (all films) even though the Necronomicon honestly speaks more to ancient astral demons that have outlived Satan himself, I like to think in these films, Satan used the book for his own twisted means after conquering the ancients.
3. Jacob's Ladder.. you know a movie left it's Mark when the creator of Silent Hill admits he pulled inspiration from this gem.
4. Event Horizon.. cause.. well it's a guilty pleasure.. I mean.. a wormhole transports a ship to Hell and back..it's not a great movie but I still enjoy it.
5. Insidious.. speaks for itself.
