I already own a couple of the films that were big influences for Kill Bill, Lady Snowblood and Female Convict Scorpion - Jailhouse 41.

I've just picked up another where the influence is very obvious: Sex and Fury (Fury anego den: Inoshika Och) (1973) - Norifumi Suzuki.

Plus its companion title: Female Yakuza Tale (Yasagure anego den: skatsu rinchi) (1973) - Teruo Ishii.

Both starring Reiko Ike and released by Fabulous Films in the U.K, hopefully there'll be more to come.

Cheers Trev.
