Not neccesarily there can't be many people on the planet who wouldn't recognise Jackie Chan and whilst he's probably the most famous, he's not the only Asian actor/actress who is well recognised. Indeed thats the great thing about thespians saying someone looks a bit like a well known one immediately paints a mental picture of them. If I told you that someone looked a bit like Kim Kardashian or Daniel Dae Kim (another good one for East Asians) or Idris Elba, I wouldn't need to give any more of a description, your own pre-knowledge would fill in ethnic appearance, sex, approximate age etc.
