In an impromptu interview at The Walking Dead's 10th-anniversary party held during Comic-Con International, CBR's Karl Keily spoke briefly with Grant Morrison about the one superhero he'd still like to tackle, the status of his Rogue Trooper screenplay, and whether fans should expect another MorrisonCon.

Karl Keily: You just wrapped up your epic, decade-long, redefining Batman run. Are there any other iconic characters you’d like to revamp next?

Grant Morrison: The Flash is the only one left that I would still do. If I'm gonna do the Flash, I want to do it as a science-fiction story like The Incredible Shrinking Man or Stephen King's Thinner, or The Fly, where you basically take a scientist and then subject him to a very simple equation. For Barry Allen, he'd just be getting faster and faster and faster -- and what would that mean? Because somewhere up there is the speed of light, and when you hit the speed of light, basically all time stops and it's the end. That's the limit. So we're watching this guy progress through it, faster and faster. By the end of Act 1, his clothes are burning off every time he moves, so he has to build himself a suit, and then he paints the suit red like a Ferrari and is just speeding around like he's on coke all the time! I want to do that as a sci-fi story, but out of it comes the familiar image of the Flash. I think that'd be totally different, just taking it from a different angle.

Whatever happened to the rumored Rogue Trooper script you were developing with Sam Worthington’s film production company?

Well, the way I wanted to do it was different than the way they wanted to do it. It’s one of those things that’s bubbling over there on the fringes, I don’t know if it’ll happen though.

Any other screenplays you’re working on right now?

Yeah, but I can’t talk about that. There’s a TV thing I’m doing right now and a movie thing, too, but I’ve signed NDAs so I can’t say anything.

Lastly, when’s MorrisonCon 2 going to happen?

It’s never gonna happen. We wanted that to be a complete one-off unique in space-time. Never again.
