Will Smith and Jada Pinkett Smith oozed with pride as they attended the London premiere of The Karate Kid to support their 12-year-old son Jaden, who stars in the film. The Hollywood couple have produced a remake of the 1984 classic which was one of the most iconic films of the decade. Jaden Smith stars opposite Jackie Chan as Mr Han, the new Mr Miyagi. The film is tipped to make Jaden a big star and his mum Jada Pinkett Smith said: "We're beyond proud to be here in London and see this big screen with our son." Will Smith continued: "I'm looking at this poster and he is not just that kid any more, this experience has added an extra element to his life, the growth and discipline and hard work and integrity." Jaden did his own stunts and learning Kung Fu meant a gruelling training schedule which he says was tough. "I was training all the time, four hours a day sometimes and it was really difficult," he said. Jaden certainly seems to have inherited his dad's talent.
