A few kissing scenes. At one point a woman shows a fair amount of leg. A few VERY minor suggestive comments (such as having no clothes).

A man is shot from behind (very little blood is visible on the hand of the person who finds the dead man). Several knife-throwing scenes (none hit their intended target). A man is interrogated by being hit on the head a few times (he is hit on the head more throughout the movie).

None.

A few scenes of smoking.

The overall setting of this story is dark (the film quality only adds to this), but not at all disturbing.
