Gal has finished shooting Wonder Woman and has moved on the JL; Part 1. Some interesting rumors coming out about this movie already! If this is true, I like it!!

"We see Darkseid in the beginning of the film in a flashback sequence. Around 30,000 years ago, the Amazons, the Atlanteans, and Man successfully fought off Darkseid here on Earth" The publication noted. "He left three motherboxes behind and that folks is what Steppenwolf is after in Justice League: Part One. That is pretty much your plot"
Also, the rumor about a war between the Amazons and Atlanteans seems to be more likely in this scenario
