Vaughn: (on why he favours the Klingons) The Klingon holds a fond spot in my heart because he was the first. When I read that role, I thought, this is perfect for me. He's a warrior, he wants to live the way he was meant to live whether it hurts other people or not. It was sheer passion. Heart of Glory, it was called, and the character is just that. You can't not enjoy a character like that. And it sort of sparked the rest of them.
