There is a facility with dismembered human body parts.
Lots of violence, though there is rarely blood. Although there is a bloody swordfight scene but this scene is filmed in black and white.
Many people are punched, stabbed, and shot. These scenes don't usually contain a lot of blood, though.
The ending sequence -SPOILERS- involves a large robot and many smaller ones and includes a lot of violence (no blood but a lot of flying robot parts).
There is a sword fight in black-and-white. At the end, one man is stabbed and a LOT of blood comes out (it appears black).
The violence in this film isn't usually very graphic, but the film as a whole has a lot of extremely harsh/disturbing themes.
