I assume this Shredder will still be some sort of military guy. Not being a TMNT
fan, that doesn't bother me at all. Does it bother you? And maybe - this is a wild guess on my part - Bay didn't want to have an Asian-American US military officer be a bad guy? Maybe he's actually trying to be enlightened.
And what's Fichtner supposed
to say? "No, thanks, throw oodles of money at some other
white dude?" I just hope they let him be his awesomely weird self.
