Sam Neill: (talking about meeting Druids while filming Merlin in Wales) A young couple with no shoes came to my hotel with all sorts of interesting observations about the old religion. They gave me a crystal. I've never believed in crystals. I've always been cynical and jaded but I got them to sew it into my costume. Day one chasing around Snowdonia on horses, the crystal was gone. I was devastated. A hundred people were searching for the crystal in 500 acres of national park. There's no way we're going to find it. 'Please stop,' I said. I put my head into my hands and looked down and in the grass between my feet was the crystal, and now I'm never without it. It's always in my roly-poly bag.
