Own the rights?
None.
Stylized violence and light blood spatters.A character kills people for a living and talks about his victims a few times. (In detail)At a sword fight near the end, one of the characters gets his hand cut off. This is the most violent act in the movie, and I would not suggest that younger children be allowed to watch it.
No language.
No noticeable alcohol/drugs/smoking.
The sword fights and battles are quite intense.
