I first saw this in the late 80s on a vhs. Revisited the 91 mins version recently.

Sonny Chiba's character castrates a rapist with his bare hands, he delivers a powerful punch to an opponent's head which is shown thru a very innovative x-ray shot of the skull being completely shattered and all this with just a mere ninja punch (fist closed n punch from ulna side). He even rips out an opponent's vocal cords by mere hands.

The film has eye horror scenes for fans of Fulci.

A man is pushed from a height n he falls down with his face down n his face getting smashed like a watermelon is downright brutal.

Coming to some comedic stuff : A fat teacher's punch in 3D comes rite at the viewer's face.

There is unnecessary isometric exercises (body parts tightened n clenched). There r unnecessary punches thrown in weird ways n there is immense obsession with the face twitching n facial expressions as if those of whistling.

In some scenes, Chiba made facial expressions as if he is trying to hold poop or as if he is whistling or as if he wants to remove phlegm/mucus from his throat. The film is a bit racist towards African American.

Watch out for Sonny Chiba's goggles n forearm armour.

How can u rip off somebody's balls by jus mere hands and later not washing the hands.

Guys during a fight duel takes too much time in twitching n contracting muscles n hand movements that one of the crime boss gets impatient n tells em to finish it off.

I first heard about this through Christian Slater's character in True Romance, so I bought it. It's a great martial arts film, Sonny Chiba does better then anyone else could in trying to fill Buce Lee's shoes. This is probably one of the best non Bruce Lee martial arts films ever. Sonny Chiba sets himself up as an eternal movie bad-ass. He is paid by people to go around kicking the hell out of other people. Good action sequence and good directing over shadow the not so great acting. This movie originally had an X rating in the United States because of a scene where Chiba castrates a man with his bare hand. It remains the only movie ever rated X not to have any sex in it. My favorite scene is the X-Ray vision skull cracker scene which later went on to be used in the ultra ultra violent Story Of Ricky.

A seriously rough, brutal and unsparingly violent mid-70's chopsocky grindhouse classic starring the almighty Sonny Chiba, a ferocious feral grunting beast of a man who portrays a blithely amoral mercenary-for-hire who winds up taking on the local Yakuza when they refuse to pony up the money that's due to him. Chiba embarks on a shockingly harsh murderous spree, literally busting heads (in one breath-taking shot we see an x-ray of a skull being broken by Chiba's death blow!), gouging out eyes, knocking out teeth, ripping out throats and in one particularly nasty scene tearing a would-be rapist's penis off (ouch!) with his bare hands. This is pure raw, graphic, unflinchingly savage and hideous in-your-face karate carnage all the way, complete with gorgeous widescreen photography, funky "wacka wacka" 70's rock guitar music, wall-to-wall no-holds-barred fight scenes, globe-trotting locations, lousy dubbing, hot Asian chicks, an annoying comic relief wimp sidekick, and a reasonably complex plot. It's also exciting as all hell, especially when Chiba takes on and subsequently takes out five or six dudes at a time. Compared to the extremely primal and lethal untamed martial arts animal that is Sonny Chiba, Bruce Lee seems like a very sweet, harmless and mild-mannered creampuff.
