THE ABOMINABLE DR. PHIBES (1971)

 One of the all-time great Vincent Price performances here. Also one of the easiest jobs for Caroline Munro as his deceased wife and the catalyst for his revenge-fueled murder spree. Killer bats, rats, locusts and even a golden unicorn are among the tools used by Dr. Phibes to wreak his biblically-inspired vengeance(I don't remember any unicorns actually being in the bible but I'm no scholar). Fun horror flick that sorta inspired SAW(but they forgot the whole fun part). AKA DR. PHIBES

 There was a sequel the next year and a planned BRIDE OF DR. PHIBES that sadly never got made.
