Justice League features Jason Momoa’s first take on Arthur Curry and it is a lot different from the character that we just saw on the big screen in James Wan’s Aquaman.
Zack Snyder earned his Aquaman executive producer title by helping to shape the Arthur Curry character.
It appears that Snyder helped James Wan steer the Arthur Curry character away from what Whedon did with him.
The fact that Snyder helped to shape the Arthur Curry character helps to cement that fact.
