Apparently not on DVD, but Taoism Drunkard plays here in Boston every few months (next time on 12 June). It's madness. On DVD, Butterfly and Sword leaps to mind.
As for Samurai... Well, Takashi Miike must have done something in the genre, right?
I would've thought so, but at least the films of his available at Netflix, he hasn't. Mostly gangster/yakuza stuff. I'm sure it'd be an interesting film though.
The films are quite good & the subtitles are excellent but for over the top Samurai violence you can't beat the Lone Wolf & Cub film series. Also check out the 2 Lady Snowblood films. The later 70's Zatoichi films get a bit bloody but nothing in comparison to the Lone Wolf films.
Not on DVD but very over the top & politically incorrect is the Razor film series.
If your looking for a really bad/stupid Kung Fu movie, might I suggest The Crippled Masters.
" This is an old-school Kung Fu movie at its most glorious. A man with no arms. A man with no legs. An undercover police officer. An evil man with a mysterious clanking back. A wise old man in a basket. Put it all together, and you got the number one must-see Kung Fu film ever."
Review from one of the greatest reviewers of our time: Brian Kissinger
Try the story of Ricky, its a live action version of the Japanese Anime called Riki-Oh. The fight scenes are just ridiculously violent and over the top. That film should satisfy you.
there are 50 kung fu genre trailers on the something weird release-karate: the hand of death.also a tip o the hat for crippled masters and master of the flying guillotine-------------dave from jersey
Don't know the name of it, but there is a martiaL arts film where some old evil guy gets an axe in his back and continues fighting and the funniest poart is that he flys around.
Don't know if it's the Lone Cub film, but there is a martial arts film where a man with a baby in a baby carriage would push the baby carriage towards his enemies and knives and swordes would come out and cut limbs off.
