Actress Helen Mirren is convinced she was destined to play Queen Elizabeth II on screen - because she used to look like the British monarch's late sister PRINCESS MARGARET. The PRIME SUSPECT star plays the royal in new movie THE QUEEN and admits she was always shocked by the family resemblance she shared with Elizabeth. Mirren, who was made a Dame in 2003, says, "When I was younger, whenever I put on dark hair to play a character, I looked just like Princess Margaret. There must be a genetic connection. "I used very little make-up and a little padding. The hair and glasses make a huge difference."
