Scottish actor Brian Cox was once a medieval knight who guarded the Holy Grail - something he discovered after he was hypnotised. The X-Men star saw himself dressed in armour with a flag flying behind him when he went through hypnotic regression, but it was not until he visited Russia with his daughter Margaret he discovered what his vision was about. He says, "I saw myself in chain mail armour. There was a flag behind me with a faded silver or golden cross on a background of red. "About three years later, Margaret was studying in St Petersburg and we went to a museum. She shouted 'dad, dad' and dragged me to see the flag I had seen during my hypnosis. I was amazed. "It was one used by the Knights Templar, who guarded the Holy Grail. So I guess I must have been involved in that Baltic crusade."
