Jaden Smith, star of the new movie “Karate Kid,” trained every day for four months in order to learn kung fu, the martial art performed in the film. Wu Gang, the stunt coordinator of the Jackie Chan Stunt Team, was hired to be the fight coordinator for the remake of the 1984 original. Wu worked 11-year-old Jaden at such a level of intensity that he cried at one point. Many of the training scenes included in the film are actual sessions that Smith experienced.
With a focus on stretching, front kicks and upper blocks, Smith has been quick to point out that the training was real and consisted of grueling, intense training. Training sessions ran from five to eight hours many days.
