I reckon two Ronald Wong Bans is unlikely:

But I also reckon there's more than one Wong Ban in the first entry - the Art Director credit at least seems unlikely... probably this guy:

Croped his face from the "best" picture and added it as portrait

Ronald Wong Ban (2) (王斌(2)) (from the movie "The Rules of the Game")

Thanks! Most definitely Ronald Wong Ban (1)
