Here’s the poster for one of the rarer and apparently one of the last of the Hammer horror freakouts. This weirdo horror flick, starring Stefanie Powers, was released in 1970. The poster is exceptional, but the trailer is…huh?

According to the movie brain trust at IMDB, Crescendo (AKA: Le Mannequin Defigure) involves “…a young American woman Susan Roberts goes to the south of France to do her thesis research on a recently deceased composer, staying with his eccentric relatives.”
Strange and off putting doppelgängers! Creepy music! Disfigured mannequins! Wow! Wow! Wow!
