This is one movie that probably would have been improved if Ed Wood had directed it instead! The whole thing plays out like a fever dream after you've eating a bad chicken salad. It's impossible to say if Jerry Warren "improved" on it or not; check out the ax job he did on "La Marca del Muerto", repackaging it as "Creature of the Walking Dead". The story of two brothers with Satanic powers dueling it out over the family fortune(and bragging rights over a kitschy-looking standing stone called the "Devil's Saddle") is barely coherent, the direction is barely coherent, the acting is barely coherent, and I was barely coherent after watching it. It was so bad it wasn't even funny--Warren seems to have that magic touch, doesn't he? The only good thing I can think about this turkey is that Bruno VeSota(a reliable Warren alumnus) didn't have to appear in it. Hmmm. Maybe if Warren had taken a cue from "Attack of the Giant Leeches"...but that's just me. BTW: I caught this on the old late-night schlock show, "Fright Night" hosted by "Sinister Seymour". When Seymour did a bumper between commercials, saying "...and we'll be right back with 'House of the Black Death'! Whaddya think of that, fringies?", they cut to John Carradine sitting up in bed and screaming in abject terror! I know how you felt, John, believe me, I do...
