Constantine exec producer Daniel Cerone has revealed that there's a possibility that another DC comic-based character -- 'The Spectre' may appear on the TV series.
Here's the EP's statement in an interview during the recent TCA press tour:
Look, I’m just bringing you in on the early creative discussions," Cerone said. "It might happen, it might not. It’s just the point you’re catching us at. Right now, episode five is off on outline. Within the context of episode five, we had a need for a police officer who sees that supernatural evils exist. Right there, okay, that’s an opportunity to introduce a DC character. So we talked to our DC representatives and we’re like what if we make this character Jim Corrigan, who goes on the become The Spectre.
For those who don’t know, Jim Corrigan is a police officer who kind of takes the law into his own hands… he ends up dying and is reincarnated as The Spectre. So it’s a perfect opportunity for us, because we can name this character Jim Corrigan and within our story, for the general viewer, that works, because now Constantine has a friend on the force.
For the comic book fan, 'My god, that’s Jim Corrigan!' And we can get back to that character and can slowly develop that character and who knows, maybe there’s an opportunity in the future to even see the origin story unfold within the framework of our TV series. It creates opportunities and creatively you just have to go in and lay that groundwork in and try and let it unfold naturally. So we’re in the midst of approvals on that, but that’s one idea we’re exploring right now.
