What if there was a martial arts movie about one of the most famous shifu in the world. Who taught Bruce Lee at an early age. Who is great at fighting. Played by Donnie Yen. Choreographed by Sammo Hung. And his main adversary is essentially the entire nation of Japan. And he never loses a fight, or even really looks close to losing, even when he has to do a kumite of a gajillion of guys in a row to get food for his family.
You're in luck, this is exactly that movie!
