EIGHT-year-old Owain Gillies really is the new kid on the block. The Huntingdonshire youngster beat more than 3,000 hopefuls to win a starring role in the latest television advert for Lego. The 40-second commercial for Lego City is being shown this week - scheduled to go out four times a day. Owain spent a whole day filming, having to do his part against a green screen. He was then digitally shrunk down to Lego size and let loose to explore his very own Lego city.
