Glass Onion: A Knives Out Mystery (titled onscreen as simply Glass Onion) is a 2022 American mystery film written and directed by Rian Johnson and produced by Johnson and Ram Bergman. It is the sequel to the 2019 film Knives Out, with Daniel Craig reprising his role as master detective Benoit Blanc as he takes on a new case revolving around a tech billionaire and his old friends. The ensemble cast includes Edward Norton, Janelle Monáe, Kathryn Hahn, Leslie Odom Jr., Jessica Henwick, Madelyn Cline, Kate Hudson, and Dave Bautista.  

Johnson had considered the idea of several films featuring the Benoit Blanc character prior to the first film's release. A sequel was greenlit by its original distributor Lionsgate in 2020, but in March 2021 Netflix bought the rights to two Knives Out sequels for US$469 million. The cast signed on that May. Filming took place on the island of Spetses, Greece, in June and July 2021, and continued in Belgrade until September.  Following its world premiere at the Toronto International Film Festival on September 10, 2022, Glass Onion began a one-week limited theatrical release on November 23, 2022, receiving the widest theatrical release ever for a Netflix film and grossing $15 million against a $40 million budget; Netflix began streaming it on December 23. 

 Like its predecessor, Glass Onion received critical acclaim, with reviewers praising Johnson's screenplay and direction, the performances of the cast, and musical score. It was named one of the top ten films of 2022 by the National Board of Review and received two nominations at the 80th Golden Globe Awards: Best Motion Picture – Musical or Comedy and Best Actor in a Motion Picture – Musical or Comedy for Craig.
