I have a vague recollection of a vampire movie where they walked a horse through the local cemetery to try to find the vampire(s), with the belief that horses would refuse to walk over a vampire’s grave. For a long time I thought that this was in Captain Kronos – Vampire Hunter but apparently it isn’t. Any ideas? Thanks!
“The Sleep of Death” (1980)?
The complete movie is on YouTube, I provided it below and you can see the vampire detection with a horse scene at 1:12:15.
