About a decade ago, Zack Snyder developed a storyline for the DC Extended Universe that involved Bruce Wayne impregnating Lois Lane.
The subplot in which Batman cuckolds Superman was poised to unfold in āJustice League,ā with Batman dying in the sequel and Lois raising their spawn with Superman. Snyderās vision for Wonder Woman was equally unorthodox, with visuals featuring a superheroine who brandished the decapitated heads of her conquered enemies like an ISIS jihadi.
Warner Bros. and DC Studios ā which hold a firm grip on their intellectual property ā rejected Snyderās ideas, which were deemed āsuper creepy,ā according to a source familiar with the back and forth. (DC declined to comment for this story. A representative for Snyder did not respond to a request for comment.) But in the next decade, artists and rival studios wonāt need permission to create their own take on the characters.
A sad fact of Hollywood is that while superheroes never truly die, all copyrights do. On Jan. 1, Disney lost control of āSteamboat Willie,ā and within 24 hours two horror-comedies starring Mickey Mouse were announced. The DC characters are the next major expirations looming on the horizon. Superman and Lois Lane will enter the public domain in 2034, followed by Batman in 2035, the Joker in 2036 and Wonder Woman in 2037.
Chris Sims, a comic book author and Batman expert, expects a flood of unauthorized Batman comics to hit the stands as soon as the copyright expires.
āThereās going to be 100 of them,ā he says. āTheyāre going to have them ready to go.ā Movie producers will also be able to make their own versions ā much as they already do with public domain characters like Dracula and Robin Hood ā though in the beginning they will have to stick to the original versions of the characters.
āYou get Batman, but you donāt get Robin,ā Sims says. āYou get Superman, but you donāt get kryptonite.ā

The initial Superman could only leap ā not fly. āThose characteristics are going to fall into the public domain one by one,ā says Amanda Schreyer, media and entertainment lawyer at Morse.
DC has been preparing for this for years. At a press event in 2023, CEO James Gunn noted that the next Superman film will introduce characters from āThe Authority,ā a comic series that launched in 1999, in part because the Superman copyright is about to expire.
Jay Kogan, DCās deputy general counsel, laid out a strategy to protect characters that fall into the public domain in a 2001 article. Since only the older versions lose protection, he urged: āKeep āem fresh and up-to-date.ā
āBy gradually changing the literary and visual characteristics of a character over time, a character owner can keep whatever the then-current image of the character is as the de facto standard in the public consciousness,ā he wrote.
The company has done a good job of updating Superman, argues Steven Beer, an IP lawyer at Lewis Brisbois Bisgaard & Smith.
āThe publicās perception is the contemporary Superman. Itās distinctive,ā he says. āThat gives them a lot of protection.ā
Another tactic: Maintain a high level of quality control.
āThe public should be conditioned to view any works from unrelated parties featuring a trademark ownerās characters as second-rate knockoffs,ā Kogan wrote.
Kogan also suggested that trademarks could be used to block the use of a characterās name, image and slogan even after the copyright expires.
But trademark is not a cloak of immunity, argues Jennifer Jenkins, director of Dukeās Center for the Study of the Public Domain. āThat only prevents uses that are likely to cause consumer confusion about source or sponsorship,ā she says.
In other words, the charactersā names should be fair game, so long as itās clear that the depiction is not coming from DC.
āYou could still create a Superman horror movie or Batman horror movie,ā says Jonathan Steinsapir, an IP attorney at KHIKS. āYou just need to be careful about how you advertise it and how you use images of Superman in a branding sense.ā
DC has done a careful job of tying the characters to itself by trademarking the terms āMan of Steelā and āCaped Crusader,ā as well as Supermanās āSā and Batmanās logo.
āThe bat symbol is a very strong mark,ā Schreyer says. āThat is going to limit what subsequent creators can do.ā
Even so, expect the mid-2030s to see a glut of off-brand superhero content.
āPeople will make a run at these characters because thereās money to be made,ā says Mark Waid, a comic book author and historian best known for his work on DC Comics titles like āSuperman: Birthright.ā āOr how about Superman versus Godzilla. Itās a gray area. But this town works on the speed of capitalism, right? Thatās how we work.ā
Sims believes more superhero comics will be a good thing. But the idea that there will be a Superman renaissance is oversold, he says.
āItās gonna come down to execution,ā Sims says. āThereās one company thatās used to doing it.ā
Steinsapir says nothing would keep Snyder from making a non-Warners film featuring the DC troika.
āZack Snyder could reshoot it and make his own new iteration of it,ā he says. āYou just need to be careful. For example, he definitely couldnāt call it āJustice League.āā
