Although I didn't plan it this way, these last three episodes of Elvira's Movie Macabre from Shout Factory DVD (see part 1 for the first three) represent early 70s exploitation versions of the three biggest Universal movie monsters: Dracula, Frankenstein and the werewolf. Also, interestingly enough, two of these flicks feature the late Michael Dunn, a dwarf actor, probably most memorable for his performance as Alexander in the "Plato's' Stepchildren" episode of the original Star Trek, and as a recurring villain on TV's Wild Wild West.
Frankenstein's Castle of Freaks (1974)
The Elvira sequences on this disk are of poorer video quality than the rest of the series, with a vertical line pattern present throughout the episode. The film itself is quite sharp, except for minor speckling that gets pretty bad at reel changes. The movie is full to the brim with "WTF" moments, which make this a fascinating and fun train wreck of a film. Shot in Italy, but set in a nameless 19th century European country, the film introduces us to Count Frankenstein who, as Elvira points out, has been a Baron in nearly every other Frankenstein film, so why is he now a Count? For no good reason that I can discern, there are several Neanderthal men living in the countryside surrounding Castle Frankenstein. One of these cavemen is beaten to death by angry villagers (and it's just not a Frankenstein movie without angry villagers, God bless 'em), making him a prime candidate for Frankenstein-ian shenanigans.
