Undercover Hidden Dragon 
Undercover Hidden Dragon is an eclectic, rather esoteric action comedy from the talented filmmaking duo of Gordon Chan Ka-Seung and Dante Lam Chiu-Yin. You'll have to have an appreciation of the comedy styling of Ronald Cheng to enjoy this film fully. There are some nice action set pieces by action director Wong Wai-Fai mixed with the loony comedy scenes. Cheng is quite good playing two roles; he had me completely fooled. My current 'most favorite' actor, Lam Tze-Chung, is featured as Cheng's buddy. They perform a musical number that you must see. Theresa Fu Wing, Miki Yeung Oi-Gan, and Ella Koon Yan-Loh get honorable mention for their work as the undercover police officers.
