Rian Johnson's Knives Out 2 title reveal might start a mystery investigation itself as the meaning of Glass Onion is explored. The director behind 2019's hit whodunnit capitalized on the movie's success, agreeing to make two sequels for Netflix. While Daniel Craig's detective Benoit Blanc returns for the sequel, he will be part of a very different murder mystery featuring a new group of A-list actor suspects, ranging from Guardians of the Galaxy's Dave Bautista to Kathryn Hahn and Edward Norton. The limited details about Knives Out 2 have created great intrigue about Rian Johnson's follow-up.

After already subverting sequel and franchise expectations with Star Wars: The Last Jedi, the story of Knives Out's sequel and the movie's title was of great interest to many. It has now been revealed that Knives Out 2's title is Glass Onion: A Knives Out Mystery. The revelation came as part of a Twitter thread from Rian Johnson where he talked about his desire to keep surprising audiences with the direction of his murder mystery movie franchise. The decision to make Glass Onion the official Knives Out 2 title has left many confused about its meaning, though.

The meaning of Glass Onion might come from a famous song by The Beatles. John Lennon and Paul McCartney created the song "Glass Onion" in 1968 as a response to the obsessive turn of their fans. The song's lyrics include references to many of The Beatles' other songs so it would confuse those looking for hidden meanings in their lyrics. With that in mind, it appears Rian Johnson could be using a similar playful irony with Knives Out 2's title. Instead of giving audiences something more traditional and plot-driven, the Glass Onion: A Knives Out Mystery title might also be meant to create a similar sense of confusion and distraction.

Of course, there is also the potential that Knives Out 2's different title direction is meant to have a more straightforward meaning. One of the reasons Lennon liked the phrase was because it represented a sense of transparency and multiple layers. This fits extremely well with the murder mystery movie genre, and it would also tease the complexity of Rian Johnson's latest story. Just as Lennon and McCartney included red herrings through references to past songs in their song, Rian Johnson might subvert the expectation of his subversion tendencies with what happens in Glass Onion.

Potentially the most intriguing meaning is that Rian Johnson will once again address some of his harshest critics through Blanc's new mystery. It can be argued that Knives Out was a response to The Last Jedi backlash faced by Rian Johnson following the release of his controversial Star Wars film, and now the Glass Onion title could be seen as a response to pop culture fandom at large. This was a small part of the first film, but Johnson could have more fun with the concept by noting just how obsessive certain sections of fans have become and how focusing on various details might mean losing sight of the final product itself. Or, maybe Rian Johnson is just a big Beatles fan and wanted the Knives Out 2 title to reference the iconic band.
