I'm guessing if Quentin Tarantino were to direct a giallo, it would end up being something like this - A bunch of folks in one location, spouting endless dialogue. I'd imagine however if Quentin were to direct it, he would neglect to add in all the bizarre camera-work and camera angles and perhaps insert a monologue by Samuel L Jackson about how someone was racist to him and then he had to bum the racists son, or whatever crap he said in the Hateful Eight.
The set up of this one is very different from your usual sixties Italian film (if you discount the fact it's set in a big mansion) - A bunch of criminals gather together to split to haul nicked from a bank in Amsterdam. It's kept in a huge tank on the grounds of the mansion and each of the criminals have a key - except for one who seems to have lost it! That means they are all stuck there until the key is found.
This is one of those films where nothing is as it seems - to begin with, the owner of the house is dead and a strange lady has taken his place, one other criminal has been replaced by a sleazy Spanish guy, and some guy called the boss keeps hovering about in a helicopter screaming about his half of the money! Plus someone is watching everyone on a camera rig (never figured out who!) and someone else is watching folk from the house owner's grave!
Add in the hyperactive camera-work, the amount of mascara these women had to wear, and the groovy music, and you've got an out there giallo that's as groovy as all those folks partying outside of the mansion (nope, never figured out why they were doing that either).
crap fact: one of the characters was played by the son of famous writer Vladimir Nabokov - that's all the fun facts this week folks! Tune in next week for another edition of Why Are You Wasting Your Life Doing Something So Utterly Pointless?
