Aquaman, the newest DC film, is no exception to this rule.
It includes a great reference to another popular DC hero, Wonder Woman, though, hilariously, the reference claims the two characters could be an item.
One of the most fun things about all superhero movies is all of the easter eggs and references that tend to get littered throughout them.
With the growing connected universe that both Marvel and DC are building, many references are to other characters that we know, while others are to comic book lore that only fans of the original books will even notice.
