Here is footage collected by the creators of Across the Forest: Tales from Transylvania (not the trailer, which I posted earlier). I assume this made it into the final documentary, because it is WILD. A man admits to making a pact with the devil to get a strigoi out of his tree. A woman describes how she pounded a nail into a corpse to end the curse of a vampire. Another guy admits to dabbling in necromancy. This looks like a fascinating film.
I am using the term "strigoi" interchangeably with "vampire." Is that accurate? Eh, kinda sorta... The Stoker scholar Elizabeth Miller has a whole discussion on whether Transylvania has "vampire folklore." I think the terms are close enough; vampires are pretty universal. But check it out for yourself.
