Problem
JLA/Avengers was one of the biggest comic book crossovers of all time as a result of Marvel and DC Comics reaching an agreement with a new story to be written by Busiek. From then on, they were purchased by Disney and Warner Brothers respectively and Bruce Timm has expressed interest in making an animated film based on the comics.

Solution
Jason Aaron and Scott Snyder agreed that they need to write a new Justice League vs. Avengers crossover. And Justice League actors Ray Fisher, Ezra Miller, Jason Momoa, Henry Cavil and Ben Affleck expressed interest in starring in a live-action Marvel vs. DC film. Even TV producers Sam Liu, James Tucker and J.M DeMatteis have stated they would love to do a crossover based on the JLA/Avengers comics. So I decided it was time to persuade Disney and Warner Brothers to give the fans the crossover they deserve. While the Marvel heroes were based on the mainstream counterparts, I would like them to have the Marvel characters resemble their MCU counterparts as such a shared universe wasn't created then.

Personal story
If this animated film is a success, then it would increase the companies' relationship and Marvel and DC would become even more of friendlier rivals than they ever were in the past.
