Solo, the latest entry in the Star Wars canon, is out, and the rollicking action movie revives -- for one film, anyway -- an erstwhile franchise tradition by getting a May release. Set between the events of the prequel and original trilogies (the six installments of which were released in the month of May), the Han Solo stand-alone nods nostalgically to the Star Wars saga's past onscreen as well. In many ways, the entire movie is one big reference.
While Disney effectively purged many beloved storylines and characters from the "Expanded Universe" novels and other ancillary material by designating them "Legends" and removing them from the official canon after acquiring Lucasfilm in 2012, the stewards of the valuable brand spent the intervening years dutifully building on the updated Star Wars canon through a steady stream of books, comics, video games, animated TV shows, and, of course, movies. Solo serves up many obvious and oblique call-backs to official canon fodder while also offering up fresh lore for future movies to draw from.
A complete list of references in Solo would involve making footnotes for the entire movie that would take as long to read as it would to make the Kessel Run in a Lambda class transport (very long). So forgive me for not getting into Han's ability to speak the Wookiee language of Shyriiwook, the very obvious inference in the third act to Han's shoot-first mentality, and more in the following list of the anthology film's most notable Easter eggs, references, and shout-outs.
