Theyre making something to entertain. Its not a documentary, it doesnt need to be historically accurate. From a historical perspective Argo was a steaming pile of lies and bullshit, from a movie perspective Argo was the best movie in the last year.
I dont think the film markers care that Keanu Reeves is white, they care that hes suited to the role of the character, that he has name recognition (i mean i just heard about this movie now and i already know im going to see it because Keanu Reeves is in it). Mostly i think its about having a name-brand actor front and center though. I mean off the top of your head name a famous Japanese actor (if you can do that, now name one with perfect american english). Odds are you cant.
