Count Dracula & His Vampire Bride [aka Satanic Rites Of Dracula] (1973)

If the plot isn't enough of a hoot, this movie is shot with a dangerous excess of 1970s style. Besides the obvious fashion victims wearing sheepskin vests, Dracula has outfitted his mansion with a mod control room, missing only lava lamps. And speaking of lamps, half of this movie is shot from behind various lighting fixtures.
