If you’re wondering what the next Superman movie might be, this could prove an interesting pointer. It seems that Warner Bros is pitching a live-action take on the Mark Millar graphic novel Superman: Red Son to directors as a potential project.

In a Twitter conversation with Millar, Jordan Vogt-Roberts – director of this year’s blockbuster Kong: Skull Island – mentioned a pitch he’d made that had been knocked back. Millar responded by saying that he understood at least two further directors had been pitched the film during talks with Warner.

Vogt-Roberts then revealed that his pitch had been declined months ago, suggesting that Warner may have had a change of heart over the idea – or that they just had other directors in mind.

The three-issue series, published in 2003, was written by Mark Millar and drawn by artists Dave Johnson and Kilian Plunkett. It takes place in an alternate reality where the infant Kal-El’s escape pod crash lands in the USSR instead of rural Kansas, leading him to become a literal Soviet Superman against the backdrop of a disintegrating United States.

Pressed for updates by Den of Geek, Millar clarified, saying “I’ve got pals at Warner Bros but never discussed it with them. I think they’re just going through their back catalogue of big books and hoping to lure in good directors as opposed to any particular interest in developing ‘Red Son’.

“There’s always 50 conversations for every comic book movie that gets made and as far as I know this is something that is very much just at conversation stage.”

We’d take all this with a grain of salt – as Millar admits, it’s less likely that Warner is pursuing Red Son specifically and more likely that they’re sounding out directors for a future Superman instalment by throwing out ideas.

A Man of Steel 2 script, following up the character’s appearance in the Justice League movies, is believed to be in active development already, though no release date has been set. As such, even if Superman: Red Son did happen we imagine we’re looking at some time after 2020.

On the plus side, that should give you plenty of time to track down the original issues as an investment.
