Superman: 20 Easter Eggs You Probably Missed
3. Adee Serrao
When Superman battles The Engineer (María Gabriela de Faría) at the Metropolis Meteors' empty stadium, you might notice a sign around the stadium reading the word "Serrao."
This might seem like a generic company name or perhaps a nod to a corporation from wider DC lore, but it's actually a playful reference to one of this film's most important crew members.
Adee Serrao was the movie's lead graphic designer, meaning she oversaw all graphic design elements of the final product, such as the various logos we see throughout the film which help ground it in our own reality.
We can't know for sure how Serrao's name ended up in the movie - whether placed there herself or by a colleague - but it's clear a tip of the hat to her superb work on the film.
