My favourite scene in "La ragazza che sapeva troppo", that Mario Bava obviously named after Hitchcock's famous "Man who knew too much".
Nora Davis is alone in a Rome flat, close to the place where she thinks she saw a murder at the very beginning of the film.
It's dark, it's windy and the windows of the flat are turned into a scary Chinese shadows theatre.
Back to primal, childish fears, where it's your imagination which scares you.
Nothing's happening just now. But it's coming.
