Thanks, I'll add those to my list! I did see a 'giallo' film a few years ago, about a girl trapped in an underground lair or something. I actually don't really like a lot of gore in films (it doesn't particularly bother me but I just don't find it interesting) and that was all just for shock value.
For what it's worth, a couple of years ago I got caught up in watching several
giallos on Shudder. They ranged from Hitchcock inspired thrillers (
The Girl Who Knew Too Much, edited for America into
The Evil Eye; or
Blood and Black Lace) to surreal horror (
Lisa and the Devil) to proto-slashers (
Bay of Blood). And those are just the ones directed by Mario Bava (who I would generally recommend, though
Bay... and
Tenebre might be gorier than you'd be comfortable with).
Those I enjoyed most included,
The Girl Who Knew Too Much/
The Evil Eye (I saw the latter version)
Blood and Black Lace (a bit more violent than
Girl but I don't recall much gore)
The Bird with the Crystal Plumage
Kill, Baby, Kill (terrible title for a good, odd, slightly surreal thriller)
The Strange Vice of Mrs. Wardh
Cat O'Nine Tails
Forbidden Photos of a Lady Above Suspicion
Your Vice is a Locked Room and Only I Have the Key (notable for all of the characters being perverse and unsympathetic, but I found the Poe-like atmosphere -- some of which was drawn from a famous Poe story -- irresistible)
I also thought
Deep Red was excellent, but it does have some gore. Otherwise, I was drawn more to those that were mysteries rather than horror. Just be prepared for entirely implausible plots.
