Characters are shot/impaled with swords, blades and sci-fi weapons with moderate visual representation of post-action blood detail.
A character poisons a room full of people. Deaths occur offscreen but audible.
The characters fight almost exclusively using close combat knives and swords, so there are several fight scenes (never shown up close but in wide angle)
Many people are drained of blood so that the Sardaukhar Army may receive blood marks on their forehead as a ceremony into their army.
A character is impaled by a dart which in turn paralyzes him.
A bit of blood and a injury detail is seen including a bloody hand and knife
Scenes include close-quarters combat with bladed weapons, including slashes and stabbings resulting in brief sight of blood. There is occasional focus on bloodied blades, or blood on hands and clothes. Other sequences depict large scale attacks in which ships and buildings are bombed and explode, and a number of deaths caused by toxic gas
A character grabs another man by the hair and hoists him up as he brings up a blade to his neck and slices. The camera cuts away but you hear the squelch of the blade decapitating the man. Next shot shows the character briefly holding the severed head before dropping it, but no gore is shown as it is blocked by a table in the foreground.
While there are not an overwhelming amount of violent scenes (unlike Dune: Part Two) the action sequences and deaths can be intense.
