Pretty slick and crazy samurai sci-fi flick!
It's an Irish movie made in Slovenia and here's the synopsis:
"Follows a scorned geisha who creates a magical cup made of tears that causes any man who drinks from it to fall into a permanent sleep. One night the cup is stolen, setting off a chain of events that threatens civil war amongst the clans. Taro, a gifted samurai, sets out to find the cup and one who can break the spell."
