When I watched this movie it automatically reminded me of Lei Wulong from the Tekken video games in playstation. The hair, the clothing, the moves, and his face had a real similarity to Lei. I think this is where Tekken got their ideas.
Blatantly - Lei has Drunken Boxing moves as well, and is a cop - a mix of Jackie's Wong Fei Hung from the Drunken Master films, and Ka Kui from the Police Stories I'd wager. Also, Law is blatantly Bruce Lee, Raven is Blade, Bryan is Roy from Blade Runner.
