Master Blaster - How'd you know!? lol
Dave, if you really wanna go on a Chiba binge then you should pick up the St. Claire Vision Martial Art's Master boxset. I picked it up at WalMart earlier in the week for about 5.00! Here's a link:http://www.littleman.com/movies/films/7/000215557.html
I already had a copy of Street Fighter on DVD, but this one has Street Fighter, Return Of Street Fighter, and Sister Street Fighter all on one disc! It also has a disc with a few Bruce Lee flicks (The Real Bruce Lee, Fists Of Fury, etc). The third disc contained what was a real gem for me: Shogun's Ninja. Great flick starring Sonny Chiba as a complete badass, and what looks to be the first emergence of Hatori Hanzo in Japanese cinema.
It also has Ninja Wars which has Chiba and a flick called Rage Of The Master which I have yet to watch. So, out of 9 films, five of them have Sonny Chiba.
Also, you might want to try hunting down a few of Chiba's better known flicks like Samurai Reincarnation (great flick!), Legend Of The Eight Samurai, Shogun's Shadow, The Bodyguard, Killing Machine, or the b-classic Message From Space.
It's good to know that you've taken an interest in Chiba, Dave. Despite Lee's popularity, I find Chiba much more entertaining.
