Digital Spy spoke with "Gotham" showrunner Bruno Heller in anticipation of this week's "Gotham" premiere, discussing not only the development and core concept of the series, but also casting David Mazouz as Bruce Wayne and the character's role as the series progresses ("The core of the show is Gordon, but Bruce Wayne will certainly play a much larger part in the show than we had initially thought," Heller said.) and the possible crossover potential "Gotham" might have in relation to a larger DC Universe.
"We'll see as we roll on. Precise tone is the important thing in establishing a series, but then you have to see what other shows live in the same universe. Would it be weird if they met up?" Heller told Digital Spy. "It's fun for the audience to see that clash, but actually doing it is scary. I hope we do at some point. That's the beautiful thing about being inside the DC Universe, but we'll wait and see what pops and what doesn't."
It's unclear whether Heller referring to new, as-yet unannounced DC Universe-centric shows on Fox, or the three other DC-inspired shows coming during the 2014-2015 season -- "Arrow," "The Flash" and "Constantine." A crossover between networks is unlikely, but the possibility isn't without historical precedent -- the "Homicide: Life on the Street" character Detective John Munch has appeared on quite a few shows outside of the show's home network on NBC.
The showrunner also briefly discussed the concept of The Joker on "Gotham," and how the iconic villain might get introduced during the course of the series.
"We're going to wait and get the show up and running [before we meet the real Joker]," Heller said. "We want to get the story right and we want to be tonally right - and then we'll start thinking about how to bring him in. We will certainly try to surprise people, and maybe even trick people. It's one of those expectations that everyone will be waiting for, so you can't just present the guy with a big smile and start telling the story. Not that that would be dull, but that's one of those opportunities to really start playing with this."
"Gotham" premieres September 22 on Fox.
