"Zach Schneider's Justice League" is based on the story of the Justice League in DC Comics. The Justice League in DC Comics first appeared in the 28th issue of the comic publication "Brave and Fearless" in March 1960. All of its members are superhero characters in DC comics, such as Superman, Batman, Green Lantern, Flash, Wonder Woman, Aquaman, Martian Manhunter, etc. The villain of the film is Steppenwolf in the extended version of "Batman v Superman: Dawn of Justice".
"Zach Schneider's Justice League" and "Superman: Man of Steel", "Batman v Superman: Dawn of Justice" and other works are in the same universe, and both are part of the DC expansion universe. With this large cosmic environment as the background and comic works as the basis, the stories of Superman, Batman, Wonder Woman, Flash, Green Lantern and many other DC comics superheroes have been integrated to build an increasingly full world system.
In 2011, Zach Schneider just started contacting DC movies. He always wanted Batman and the Joker to meet on the big screen, but he was eventually put on hold after falling out due to his relationship with Warner. In 2020, HBO Max intends to restart the "Zach Schneider Edition Justice League" plan to bring this idea back to life.
