To use the genre parlance, James Wan's Aquaman is primarily a solo character adventure, being set after the events of Zack Snyder's Justice League, but it is also an origin story. Part of the film's mission is to explain where the eponymous hero comes from and who he is meant to be, and as a result there are segments of the narrative dedicated to his past. Specifically, there are numerous flashback sequences throughout the blockbuster -- and while I was on the set last year, I learned key details about a few of them.
