Just watched this on TV (in Italy).
The last of Shinya Tsukamoto movies, and also third in the Tetsuo trilogy:
Tetsuo: The Iron Man
Tetsuo II: The Body Hammer
Tetsuo: The Bullet Man
The first, in black & white, is still the very best. A cult movie and absolute masterpiece where every frame is pure visual and symbolic perfection. The swapping pics of the header of this site are frames from that movie.
That first movie was also done in low budget more than 20 years ago. The new one was done in 2009 and is still strong in symbolic value (closer to a remake than a new story), even if the streamlining of the plot wasn’t necessary and weakens the message and value. The music at the end is done by Trent Reznor, even if he can’t surpass his master, Chu Ishikawa.
I’ll try to add pictures later.
