Masked heroes I can at least see... those don't even exist in the real world either. And besides, they probably thought seeing Zorro would make it look like Bruce got as much inspiration from the Zorro character as his parents murder, thus taking some of the impact away from the murder.
But... turtles don't exist in Kaneko's Gamera-verse? F*cking TURTLES?! One of the oldest animals on the face of the earth? Doesn't exist in the Gamera trilogy cuz... why again? Because Kaneko can't seem to deal with the fact that a giant turtle is a ridiculous idea? So he just says "Oh, there are no turtles here." Bullsh*t. Total bullsh*t. What difference does it even make? Just don't show a turtle or say the word "turtle."- Don't go marching around saying it takes place in some turtle-less dystopia.
I always thought the guy was pretentious, but that's not only the dumbest thing I've heard him say, it also might be one of the dumbest things I've seen any director say. You made a movie about a giant turtle. Deal with it. As much as I love the trilogy (FOR REALZ), the guy really seems to have a lot of contempt for the Gamera character... he can't even own up to the fact that he's a turtle!
Oh well, at least its hilarious, even if he doesn't mean it to be.
