fear enough when he was the Red/Blue Blur, but when he was just The Blur, the long black coat, and top with the S shield on it, its alot more costume like, if not the traditional Superman costume.
Let me try to get this across one more time. I never said he wasn't willing to wear any kind of
costume; he wouldn't get very far as an actor with that attitude. I said that he wasn't willing to wear the Superman costume
specifically. There's a big difference, sartorially, between wearing a logo t-shirt and black duster and wearing tights and a cape in bright primary colors. Many today would consider the latter quite silly or embarrassing to wear.
