The Vampire's Ghost is tepid at best. The story takes place in Africa where drums beat constantly and everyone is whispering about vampires. That's about it. Seriously! Nothing exciting takes place and when the vampire is finally revealed he looks like an addict in an Ambien haze. Furthermore, the ending where the vampire meets his demise [This should NOT surprise you in the least] is painfully predictable and formulaic.
The acting in The Vampire's Ghost is fine but nothing notable. The actors have very little material to work with but give it their best shot. This film might have worked well in 1945, but it doesn't translate well to modern audiences. There are lots of great horror films from the 1940's. I suggest you search my site and look at one of those instead.
