Braindead, AKA Dead Alive (1992)
Lifeforce (1985)
From Beyond (1986)
Pan's Labyrinth (2006)
Midnight Movie (2008)
Nightbreed (1990)(supposedly, SyFy is working on some kind of TV series version of this, but as of now it doesn't exist yet, so I think Nightbreed is fair for this list)
Behind the Mask: The Rise of Leslie Vernon (2006)

1. Don't Look Now (1973)
2. Eyes Without A Face (1960)
3. Audition (1999)
4. Onibaba (1964)
5. Angel Heart (1987)
6. A Tale of Two Sisters (2003)
7. The Haunting (1963)
8. Rosemary's Baby (1968)
9. Suspiria (1977)
10. The Wicker Man (1973)

..or something like that...

The Haunting, Suspiria, and The Wicker Man have all been remade. And I believe there is a made for TV sequel to Rosemary's Baby.

I am aware of those but he didn't mention anything about the originals. The criteria said "no remakes" and they're certainly not part of a "series" so...

But Markus...I believe that means films that have remakes do not fit the criteria?

Bah, humbug! I will reconsider my list...

Suspiria is also part of the so called Three Mothers Trilogy

Eaten Alive '76

Motel Hell '80

Megan is Missing '11
Bone Tomahawk '15

I'm working on a second list here.

Blind Beast (1969)
Prince of Darkness (1987)
Freaks (1932)
Don't Look Now (1973)
The Sentinel (1977)
The Devil's Rain (1975)
Race with the Devil (1975)
Christine (1983)
The Brood (1979)
Captain Kronos -- Vampire Hunter (1974)

I remember watching The Devil's Rain on tv a lot, and that was an awesomely weird desert horror story. Ernest Borgnine was the man! And everyone melts at the end for several minutes.

And Captain Kronos would have been a great series if it took off. I thought that movie was the coolest when I saw it on AMC (same channel I watched Devils Rain). I'm very happy to say that I met Caroline Munro at a convention a few years back, and she's aged rather well.

Children Shouldn't Play with Dead Things (1972)
The Gore Gore Girls (1972)
Fascination (1979)
House on the Edge of the Park (1980)
Silver Bullet (1985)
StageFright (1987)
Monkey Shines (1988)
Pin (1988)
Lord of Illusions (1995)
The Faculty (1998)

Isn't Cat Girl another adaptation of Cat People?

More of a ripoff.

Cannibal Holocaust
Dead Alive
Repulsion
Deep Red
Videodrome
Brain Damage
Torso
Shivers
Near Dark
Santa Sangre

One could argue that Brain Damage is part of the Henenlotter continuity, seeing as how Duane and his basket cameo in the film.

And while I've never seen any of the "sequels", I know there are at least 2 bastardized Italian cannibal knock-offs that call themselves "Cannibal Holocaust 2".

If Shaun of the Dead doesn't count, then neither does Prince of Darkness.

Ouch, that sucked. I had to Google that, I didn't know what you were talking about. I didn't even think of the Apocalypse Trilogy. But, I was just screwing around anyway, I think both SotD and PoD should definitely count.
