DEADLINE has a great interview with THE PENGUIN showrunner Lauren LeFranc, which you should read in full (or listen to the original podcast). However, here are a couple of highlights regarding a potential second season of THE PENGUIN and other THE BATMAN spinoffs on HBO…
THE PENGUIN Season 2
Beyond Colin (Farrell), it depends on whether there’s a story that we can make richer than what we’ve already done. I fully arced everything (in terms of keeping THE PENGUIN a limited series). I’m in the process of exploring what that would be, if there will be more.
More THE BATMAN HBO Spinoffs
We’re in the early stages (of developing THE BATMAN spinoffs).

Matt Reeves has mentioned previously that they’ve got some ideas for more THE BATMAN spinoffs, so as Lauren LeFranc says, they’re probably kicking around and spit-balling what they could do and what would work. Check out the full interview below. – Bill “Jett” Ramey
