[Mike Scott]

SHE ?

SHE ?

Good guess but not just supernatural/mystical as in She. Think demonic evil.

The Devil's Hand?

[horrorhunter]

The Devil's Hand?

Nope.

Time for a hint: It mixes different legends in a wild chaotic cocktail. This flick is pure drive-in heaven, or Hell, depending on how you look at it. 

[horrorhunter]

Here's the next...

Men go off seeking a treasure and encounter a beautiful woman who intends to reunite with her lost love...even if it means invoking Powers Infernal. 

Another day, another hint: One of the actors plays a dual role as twins. That should narrow it down. 

Bonus hint: The beautiful woman not only invokes Infernal Powers, she's fairly malevolent herself...in a hot, ruthless, demonically ritualistic, sorta way.

Another hint: This film also features bathing in blood.

[Mike Scott]

One of the Elizabeth Báthory movies?

[marsattacks666]

Countess Dracula (1970)

[horrorhunter]

One of the Elizabeth Báthory movies?

No. There are a lot of bits of different legends used, so the bathing in blood probably came from Bathory. Also, the character is a countess.

[horrorhunter]

Countess Dracula (1970)

Nope. Wrong country but right time period.

Another hint: The actor who plays twin brothers had a lead role in one of the early AIP/Poe/Price films. He was also in a cool Eurohorror flick featuring Queen Of The Vampires. *nudge, nudge*    (a nudge is as good as a  to a blind vampire bat)

[Memphremagog]

The Devil's Wedding Night

[horrorhunter]

The Devil's Wedding Night

That's it. Raise HELL!
