Ethan Hawke talks sex, death and knights
Even the rich and famous have trouble with hard-hitting family conversations about life and ethics - just ask Ethan Hawke.
The Hollywood star has written a book to help start a dialogue with his children, and provide guidance for parents and children around the world.
In Rules for a Knight, the four-time Oscar nominee and father of four outlines 20 guidelines to living a better, and more principled, life.
He tells the BBC's Jane O'Brien about his frustrations that parents today teach their kids about sex, but not ethics.
