Actor Will Smith has denied reports his nine-year-old son JADEN will be taking the lead role in an upcoming remake of 1984 movie THE KARATE KID. Smith's production company Overbrook Entertainment is making the new film, which will be directed by the Hollywood superstar himself. But speculation the Men In Black star's boy will take on the lead role, which Ralph MACchio played in the original, are "not true", according to a spokesman for dad Will. Smith teamed up with Jaden when the two played father and son in the movie The Pursuit Of Happyness.
