"Then it was based on the voice of a character I did, Lothar of the Hill People. But, I would do it for 10 minutes and couldn't talk for three days. It took too much out of me.
"I have some Scottish blood. Scottish people are the salt of the earth. They are also capable of being very angry, but then very loving.
"I thought that would be perfect for an ogre. It is also a working people's accent. I feel ogres are working people. I seriously put that much thought into it."
