Speaking to IGN, Arrow producer Marc Guggenheim was asked if their version of Oliver Queen would soon have some comic book help from the DC universe, and he responded:
"I would say, "Probably." One of the things we want to do is roll the show out at the right pace. For the most part, I think we've taken the philosophy that things are happening sooner rather than later. I always feel like every time we get the note from the network, "Is this happening too soon?," I feel like we're on the right track. I know as a viewer myself, I'm impatient. I want to see stuff. We're not going to make the audience wait to see characters, plot twists, revelations. I think running out of great characters and great moments is a quality problem to have, and I just want to have them."
When pressed on who his super friends might be, Guggenheim said they're still working out the mythology—but noted that the end of Christopher Nolan's Dark Knight film trilogy could free up Bruce Wayne for a trip to Starling City.
The producers of Smallville famously tried (and failed) to bring Batman to the show, but were always stopped due to fear it could confuse fans of the film series. With the film series done, Guggenheim thinks he'll have a lot more wiggle room as far as the Caped Crusader is concerned:
"Oh, my hope is that we can use him at some point. I think that plagued the Smallville showrunners more than it plagues us because, obviously, the Dark Knight Trilogy is over. They're not available to us yet. My hope is that they'll be available to us at some point. That would be awesome. No question, that would be absolutely awesome. But I don't know. That's above my pay grade."
