Credits Designer Chen Lao-San

He has only one entry: http://hkmdb.com/db/people/view.mhtml?i ... ay_set=eng
and I suppose it's an Alias for Jackie Chan (Chen Old Three) because he composed the funny
credits sequence with several jokes and him appearing in various disguises

BTW: I supose the filming location was Korea

According to Jackie Chan's early friends, Jackie Chan was very kind and feudal in his early years. He would have a special affection for the staff with the surname "Chen" and take extra care. Jackie Chan's agent is Chen Ziqiang, assistant Chen Desen, and the film director likes Chen Kexin and Chen Jia. The photographers are Taiwanese Chen Dao, Chen Lao Second, Chen Lao San, and Chen Lao Si.

Great find! OK cancel that idea, but could have been - anyhow no credit for creating the credit sequence for Jackie....
