Twilight of the Warriors: Walled In

In 1980s Hong Kong, troubled youth Chan Lok-kwun, a mainland refugee, struggles to survive in the Kowloon Walled City by joining underground fights. Betrayed by crime boss Mr. Big while trying to buy a fake ID, he steals drugs from him and seeks refuge in the Walled City, where he encounters Cyclone, a compassionate yet authoritative crime lord.
The younger gens would not appreciate this but those "old" people like us grew up watching so many Hong Kong movies would. It would be a while (or never) to have all these cool actors all in a movie again.
