The site of the lighthouse where Arthur Curry grew up, Amnesty is a major part of Aquaman’s backstory, and one could easily draw similarities to the Kent farm from Superman’s corner of the DC mythos, or Wayne Manor in Gotham City.
Knowing that we will see this locale show up at some point means Aquaman’s origins will be explored over the course of the film’s story, even if Aquaman doesn’t necessarily opt for a full-blown origin story.
It’s striking to see that picture and realize how much the version of Amnesty Bay from the 2018 Aquaman solo movie (actually Hastings Point in Australia) looks like the version of the location from the comics — particularly with how many visual liberties the DCEU has taken so far.
