Johnny -
The only other movie I know of by this guy is "Ceremonia Sangrienta" ("Countess Dracula"). It's pretty hard to track down, but well worth the effort. It's the story of Elizabeth Bathory - and is probably the best version of her tale.
Although I have not yet seen "Let Sleeping...", I've picked it up several times. Thanks to your review, I'll be buying it tonight. Hopefully, my date won't mind a few zombies joining us on a rainy Friday night.
