Louis Koo Tin Lok's Media Asia film DON'T GO BREAKING MY HEART (DAN SUN NAM NUI) is a love story between two men and a woman. He and Daniel Wu (Ng Yin Cho) kept trying to win Gao Yuanyuan's heart. Ng Yin Cho and Goo Jai had to fight in the film.
Goo Jai said, "The only real scene with Ng Yin Cho was a fight scene, as soon as we saw each other we fought!" They spent almost two hours from rehearsal to positioning to the actual shoot. After the shoot they not only did not feel tired but honestly said, "We haven't fought so hard in a long time! Bumping back and forth like this was a lot of fun!"
Ng Yin Cho jokingly complained about constant injuries at Goo Jai's hands. "10 years ago when Goo Jai and I worked together for the first time on a close combat fight film I was already injured; I never would have guessed that 10 years later when we got together and fought over a girl he would injure me again."
In the story Goo Jai saw Ng Yin Cho at the office and fists flew without another word. They rehearsed many times before hand without any accident. Yet during the real shoot, Goo Jai missed his mark. Ng Yin Cho and Goo Jai have worked together many times and privately were
good friends. He of course did not blame Goo Jai.
