|Arrow will be "darker and harder edged" - OK, we get the point.
As for the pilot itself, director David Nutter says he is drawing on his experience from helming a certain other super hero series in the DC Universe:
“When I directed the pilot for Smallville, I knew that making Clark Kent relatable would be the key to audiences believing in him as a hero. Arrow is a different show — darker and harder-edged — but it’s the same core idea. We’re creating a real, believable world in which Oliver Queen can do incredible things. [Costume designer] Colleen Atwood’s great work on the Arrow costume reflects that effort.”
