Thought I'd revive this thread as it was before my time!
I have to say I love gialli, my favourites being (in no particular order):
- All the Colors of the Dark
- The Bird with The Crystal Plumage
- The Black Belly of the Tarantula
- A Blade in the Dark
- The Bloodstained Butterfly
- The Case of the Scorpion's Tail
- The Cat O' Nine Tails
- Deep Red
- Don't Torture a Duckling
- Four Flies on Grey Velvet
- In the Folds of the Flesh
- The Killer Must Kill Again
- A Lizard in a Woman's Skin
- Murder Rock
- My Dear Killer
- Opera
- The Perfume of the Lady in Black
- Plot of Fear
- Puzzle
- Tenebrae
- Torso
- Watch Me When I Kill
- What Have You Done to Solange?
- Your Vice is a Locked Room and Only I Have the Key
There are also a couple of 'grey area' titles that I really love that are considered gialli by some, but not others, such as Bay of Blood, Phenomena, and Stagefright - all faves of mine.
