Banquo is murdered, but we do not actually see him killed, just the swords slashing up and down

Banquo's ghost is later seen covered in blood to haunt Macbeth for his murder

After King Duncan is murdered off screen, Macbeth then kills both of the sleeping servants with his sword

There is plenty of violence, but nearly all of it takes place offscreen.

No profanity whatsoever.

Very mild violence.
