Every year since 2008, a film installment based on a young adult book franchise would be released around the same time in November that Wonder is released, with The Twilight Saga in 2008, 2009, 2011 and 2012, The Hunger Games series in 2013, 2014, and 2015, and the Harry Potter/J.K. Rowling's Wizarding World series in 2010, and 2016. Wonder would be the first film adaption based on a children's novel in this slate.
RJ Palacio got the inspiration to write the book after taking her son out for ice cream, where they saw a child with Treacher Collins Syndrome. Her son cried at the sight of this boy. This story is used in a scene from the film, where Jack Will's mother is reminding him why it's important to make Auggie feel welcome.

Miranda's nickname for Auggie is "Major Tom". This is taken from the David Bowie song "Space Oddity", which is about an astronaut named Major Tom.
