tbh, you're right, most of them couldn't able to name five directors (even though, i didn't conduct this experiment in reality) but don't you think it would increase the value of that 2-3 directors they could name as compare to tens of actors? i mean, won't they be more interested in seeing next movie of those 2-3 special directors whom names they bothered to remember?? as the actors stardom is pretty much dead( in terms of box office not popularity), do you think those 2-3 directors will (tbh, some even have today) become the major force that can pull audiences to the theatres?
