This is just a movie version for a long-standing series in Taiwan. It's the national pride over there since the puppeteering techniques were passed from father-to-son. And like father-to-son all the voices you hear are done by the puppeteer. The main character and his side-kick are old characters. As is his arch-rival (don't know how to pronounce his name but he's easily distinguishable since he's the puppet with the best looks).
In the movie all the sets are made in proportion to the puppets whereas on TV all you see is the back-drop and a stage so this movie is definitely worth seeing if you're into this kind of stuff.
