Timcop’s review published on Letterboxd:
or GASLIGHT CONSPIRACY
Sergio Martino is probably only the 3rd or 4th greatest director of giallo, depending on what films you consider giallo from some of the more preeminent Italian horror directors, but that still means he's an absolute master of the genre. And Martino is probably the king of the giallo-based dream sequence: everyone of his bizarre, surreal fantasies going off the rails in a brain melting, trippy haze. Good score, great locations-it's impossible not to want to plot to steal someone's inheritance in the most cumbersome way possible after watching this.
