Defined in the glossary: Giallo, Krimi
The one usually called the first giallo. Still half a krimi.
The film usually credited as the first giallo, though it is still half a Hitchcock homage in crisp black and white. A tourist in Rome witnesses a murder, is believed by no one, and gets drawn into a series of alphabetical killings.
Mario Bava is inventing the template in real time here: the foreign witness, the murder nobody believes, the amateur turned investigator. The colour and cruelty the cycle became known for are not here yet, but the skeleton is.
More charming than frightening, and the origin point for everything on this shelf.

Written about
- The giallo, 1963 to 1976
A line of yellow paperbacks, a killer in black gloves, and Mario Bava building the American slasher a decade before Hollywood cashed the cheque.
Filed alongside
The College Girl Murders
The point where the black-and-white krimi tips over into full-colour giallo delirium.
Alice, Sweet Alice
American giallo in Catholic New Jersey. Genuinely disturbing and well acted.
Don't Torture a Duckling
Fulci's best film and his angriest. A giallo about mob justice in a village.
What Have You Done to Solange?
Unusually sad for a giallo, and much better for it.
Opera
Needles taped under the eyes so she cannot look away. Argento's last truly great film.
The New York Ripper
Genuinely nasty and hard to defend. The killer quacks. It doesn't help.
A Lizard in a Woman's Skin
Fulci does psychedelia. The dog scene got him prosecuted.
Torso
Sleazy for an hour, then a brilliant silent final act.
Four Flies on Grey Velvet
Argento's third. Unavailable for decades, and worth the wait for the last shot.
The Cat o' Nine Tails
Argento's least favourite of his own films. He is roughly right.
Blood and Black Lace
The template, and still the best-looking film on this list.
All the Colors of the Dark
Satanic paranoia in Swinging London. Edwige Fenech is excellent.
