Then comes the voice. A huge part of the film’s charm is Stephen Chow’s performance as Sing. His voice—nasal, whiny, full of false bravado that cracks into a boyish squeak—is the sound of a loser dreaming. It is not a heroic tenor. It is the voice of a man who has never won a fight in his life. An English dubbing, no matter how talented the actor (the existing official dub is serviceable but flat), cannot replicate this. Why? Because English dubbing forces a choice: do you cast a comedic voice (losing the pathos) or a dramatic voice (losing the comedy)? The original Cantonese voice does both simultaneously, because the language’s natural pitch contour and the actor’s delivery are inseparable.
Conclusion
In the Cantonese original, the insult is biologically grotesque. The Sony version changed it to "pregnant" to make it palatable. The literal version keeps the weird, biological randomness of Chow’s humor. english version of kung fu hustle
