I have watched Operation Condor a couple of times. Jackie Chan films always have a hot leading lady, and that girl in Operation Condor is on fire!
In the 50s, 60s, and 70s, Hollywood made a lot of movies with Asian themes that incorporated a lot of deprecating "Asian humor." Ever since these "Asian humor" has come to be associated with Asian films, Asian culture, and Asians in general. Being an Asian, I don't find these "Asian humor" funny, I actually find them insulting.
Jackie Chan formulaically incorporated elements of these "Asian humor" into most of his movies. Well, I guess this formula still appeals to a lot of audiences, Eastern and Western alike.
