Esther Mok performing as Tarzan, an imaginary purple and green face gorilla in The Enigma by John Patrick. This was an ICS production performed in January, 2009 at the Lu Kao Hwa Theater, Hong Kong. This was the first time Esther performed a role that requires 100% physical actions and no spoken lines. Through this experience, she has learnt more about the importance of body movement and its impact. It has also challenged her to become a better performer that demands a strong stage presence without using spoken words.
