Where can i find a movie about succubus or incubus?

There are a few movies called exactly that, but they don't look very good.

It's really hard to build a plot line about that stuff. Incubusses and sucubusses simply show up looking gorgeous, have incredibly hot sex with their victim, then devour his / her soul and drag it to hell for all eternity, and end of story.

It's just too difficult to make a whole movie out of that. I suppose you could work it into a porn plot, but nobody ever watches porn flicks for the plot. That's why nobody has made a movie out of old Bloody Mary. You say her name in the mirror, she shows up and scratches / scares / kills you, and the end. Movies need something to keep the story going, and some stories are just too short to make good movies out of.

Try the 1974 movie, The Entity, with Batbara Hershey which was based upon a true haunting.

At the cemetery..think I'm kidding?
