The best heroes and villains are often reflections of each other. Think of Sherlock Holmes versus Professor Moriarty or even Luke versus Darth in Star Wars. There's something of each in the other. This theme has been playing out for years in the martial arts and gangster films of China and Hong Kong. Besides helping American movies make action exciting again, Hong Kong cinema has brought competition and Eastern philosophy together. Produced by Jocelyn Gonzales.
