It took Abang Adik actor Jack Tan three months to train to play badminton like a professional for the new film Gold.

Furthermore, the 33-year-old had to learn to play with his left hand, which is not his dominant one, as he is portraying national para badminton champion Cheah Liek Hou who plays with his left hand.
