This is a really weird parody dub of The Chinese Connection.
It’s extremely low quality, the new voices don’t try to match the mouth movements, there’s no sound outside the new dialogue and droning jazz soundtrack. Once in a while, there are some sound effects, but not always. During fight scenes, you can hear some of the actual audio, but most of the time it’s muted.
This one scene, where the Japanese guy calls Bruce “sick man of Asia”, is changed to the guy just saying “look at this guy, he’s funny looking.”
Honestly the funniest part of the movie, along with the scene where Bruce is leaving the karate dojo and hits the wall, and the Japanese guy jumps up and yells “who’s breaking shee-it?!”
The plot is altered to he about a rival gang stealing Bruce’s “master pimp’s” Cadillac keys.
A narrator pops in to explain occasionally that the gangs have resorted to martial art because there aren’t any guns after the LA riots.
