MARC GUGGENHEIM: It actually started with Greg Berlanti. He had made this big deal with Warner Bros. Studios. Greg and I had done Green Lantern together, and he was thinking about which DC Comics characters would translate to television. He thought Green Arrow would be a really good one because the character is really grounded. If you look at the history of comic book characters on television, the series that have had the most success are the ones that hue a little bit closer to the street level superheroes than the more cosmic level superheroes. So, he approached me and asked if I would do it with him. We talked to the studio and to The CW, we brought Andrew [Kreisberg] in, and Geoff [Johns] has been involved, at every stage. It’s just been a hive mind at work. But, there was never really a discussion of, “Hey, we should do this as a movie.” It was always like, “Okay, what DC comic book characters do we want to do as a TV show.”
