Aquaman director James Wan showed IGN and other members of the press roughly fifteen minutes of footage, and revealed more about the comics and films that inspired his upcoming DC comic book movie, during an edit bay visit at Warner Bros. in August.
While I won’t go into a blow-by-blow breakdown of the footage due to heavy spoilers, I will say that the footage showcased the film’s colorful visual palette, the Romancing the Stone-esque nature of Arthur Curry (Jason Momoa) and Mera’s (Amber Heard) relationship, and more of the production and costume designs of Atlantis and its citizens.
We were shown the movie’s opening prologue, which depicts New England lighthouse keeper Tom Curry (Temuera Morrison) finnding Queen Atlanna (Nicole Kidman), nursing her back to health, and them falling in love, culminating with the birth of their son, Arthur. Atlanna, though, is a renegade from Atlantis so when white-armored Atlanteans with laser weapons show up to bring her home, she’s forced to make a difficult choice that will affect her young son for the rest of his life.
