The Girl Who Knew Too Much - 1963 - 5/10
AKA - La Ragazza Che Sapeva Troppo

American turista, reading too much pulp fiction (Giallo) arrives in Rome and is soon in a mystery.
Restless, she walks the streets late at night, is robbed, then witnesses a murder.
Police investigate, there is no corpse, there is no blood.
One wonders how fanciful Nora is. She is engrossed with trashy books, and accidentally puffed marijuana cigarettes during her arriving flight.
Memorable camerawork, outstanding exterior locations boost what is considered “the first Giallo.”
Nevertheless, the story is a trifle, undermining the tension with romance and comedy.
