Trivia: When signing the International Superhero Accord, all the Ambassadors, save Henrietta Selick, are name of various crew members that worked on the film. For example, Alan Broiler was the supervising animator. That said she's clearly a reference to Henry Selick, a graduate of California Institute of Arts like director Brad Bird, who went on to direct The Nightmare Before Christmas and Coraline.
