Like I tell everyone else, if it's legit and its not a prank, then I can't sit here and say the possibility of Bieber playing Robin will be good or bad. I have no hard evidence to support a judging presumable failure for a role other than the general disdain or animosity for the young man's success within media presence. There could be so many other actors out there less qualified for Justin to be cast as the role, and again that's a presumption as well. All in all, I'm going to stick with a rough rule of thumb; I won't pass my ultimatum of his performance of the supposed cast until I've seen my evidence.
