Joss Whedon stepped in to finish Justice League for Snyder after the filmmaker decided to step down during production to spend time with his family.
Shortly before Whedon signed on for Justice League he had signed on to write and direct a Batgirl movie for Warner Bros., based on the adventures of the classic Dark Knight sidekick and hero in her own right.
But with basically no progress to show for almost a year of development, The Hollywood Reporter now says Whedon is departing the project.
It looks more and more like Aquaman is going to be a huge test for this current slate of DC movies.
