Moving on, and upping the sleaze and the sense of the bizarre we have...
In the Folds of the Flesh (Nelle pieghe della carne) (1970)
This is a very bizarre early '70s giallo directed by Sergio Bergonzelli and starring Eleonora Rossi Drago, Pier Angeli, and Fernando Sancho.
Speaking as someone who has seen their fair share of gialli over the years, I have yet to come across one as bizarre as this. Mixing a dysfunctional family; including an unhinged daughter who often goes into murderous trance-like states, with pet vultures, Nazis and nymphomania this is not only sleazy and strange, but also unconventionally enjoyable. Whilst I do like my standard more formulaic gialli, it's a rare treat to come across one such as this that defies the atypical genre boundaries somewhat.
Even if you're a casual fan of the genre, I'd recommend tracking this one down; The US Severin DVD is a very decent release.
