Millarworld

 ( Netflix ) 

In September 2008 it was announced that the yet unfinished War Heroes had been optioned by Sony Pictures Entertainment, with Michael De Luca as producer and Millar taking an executive producer role.

Millar has stated that whenever he sells the film adaptation rights to one of his creator-owned comics properties, he gives half of the money to the artist who illustrated the comics, despite his agent's reaction to this, saying, "Everything, all the money from the advance, the toys, the games, 50–50, so it's fair. I see it as a collaboration. If I drew, I could keep everything for myself, but I actually like the idea of having a talent that I'm not selling. One of my friends said, 'You could make even more money by drawing, too,' and I said, 'Yeah, and I suppose I could make even more money by lap dancing. It's nice to have something that's just for me."

On 7 August 2017, Millarworld was acquired by the American streaming media company Netflix.

The first comic book series that Millarworld published post acquisition was The Magic Order. The first issue was published on 13 June 2018.

On 17 July 2018 it was announced that Netflix had started work on the first set of films to be adapted from comics. These are: Empress, Huck and Sharkey the Bounty Hunter. The comic book series Jupiter's Legacy and American Jesus will be adapted as television series.

On 6 December 2018, Millar provided an update to the progress of the Millarworld properties adapted for Netflix. Jupiter's Legacy would be the first television series announced, with Steven S. DeKnight as planned as showrunner (before Sang Kyu Kim took over following DeKnight's exit from the series), with The Chosen One (based on American Jesus) as the second live-action television series released, with Everardo Gout and Leopoldo Gout as the showrunners and Gout serving as director. Empress, Sharkey the Bounty Hunter and Huck are scheduled to be feature films in development. Under Netflix, Millar will exclusively adapt new Millarworld properties to the streaming service, with select properties having comic book tie-ins, starting with Prodigy.

On 11 March 2019, Netflix announced that it would produce an anime series based on Supercrooks. It was produced by Bones.

In late 2022, several updates on Millarworld production were given, including that Huck would be redeveloped as a TV series as opposed to a movie and that a live-action Supercrooks series would follow Jupiter's Legacy after the show was canceled after its first season. That same year it was announced that Millar would be launching four brand new comic series ( Night Club, , The Magic Order 4 and The Ambassadors) and that they would lead into a crossover event entitled Big Game, which would be illustrated by Pepe Larraz and serve as a crossover between every Millarworld property.

In May 2023, it was revealed that Big Game is actually a sequel to Wanted, Millar's first creator-owned work, and follows Wesley Gibson and the Fraternity teaming up with Matthew Anderson / Nemesis to take down the latest wave of superheroes that have popped back up in the world following the actions of Dave Lizewski / Kick-Ass.

In December 2023, it was revealed that Millar had signed a deal with Dark Horse Comics to become the new publisher of the Millarworld titles. This includes reprints of previous Millarworld titles and new series, with five brand-new series launching in 2024, one of them being with artist Valerio Giangiordano.
